INSERTABLE ELECTRONIC DEVICE AND METHOD FOR THE SAME

BACKGROUND
Field

The disclosure relates to an insertable electronic device and a method for operating the same.

Description of Related Art

Various kinds of electronic devices are widely used by consumers in modern times.

An electronic device may have a physical structure (for example, slot, socket, or connector) into which insertable devices (or modules) supporting a specific function (for example, communication function) can be inserted. An electronic device, when an insertable device is inserted therein, may be electrically connected to the insertable device and may use a specific function supported by the insertable device.

There have recently been increasing demands for insertable devices providing various functions for electronic devices, and there is thus a need to implement a technology for securing stability of insertable devices inserted into electronic devices.

The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

An insertable electronic device (for example, communication module based on M.2 standard) may be inserted into a slot of another electronic device (for example, note personal computer (PC)) (hereinafter, referred to as host device). When an insertable electronic device remains inserted into a slot of a host device, the insertable electronic device may be fastened to the substrate (for example, main board) of the host device by a fastening member (for example, screw). A ground pad implemented on the substrate of the insertable electronic device contacts a ground pad formed on the substrate of the host device as a result of fastening, and electric stability of an operation for a specific function (for example, 5^thgeneration (5G) communication) supported by the insertable electronic device may be secured as a result of electric connection between the ground pads resulting from the contact. However, if the insertable electronic device is abnormally fastened by the fastening member, thereby failing to secure contact between the ground pad of the insertable electronic device and the ground pad of the host device, operation degradation (for example, signal quality degradation) may occur due to the failure to secure electric stability of the insertable electronic device.

Aspects of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. According to various embodiments, an electronic device and a method for operating the same may use a control circuit implemented to detect whether or not an insertable electronic device is fastened to a host device such that, according to whether or not the fastening is detected, the insertable electronic device is controlled to perform an operation, thereby securing electric stability of the insertable electronic device. In addition, according to various embodiments, an electronic device and a method for operating the same may use a control circuit implemented to detect whether or not a ground pad of an insertable electronic device and a ground pad of a host device contact each other such that, according to whether or not the contact is detected, the insertable electronic device is controlled to perform an operation, thereby securing electric stability of the insertable electronic device.

Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments.

The floating conductors 422 and 426 may be disposed to be spaced apart from the at least one ground conductor 423 and 427, and thus may be electrically disconnected therefrom. The floating conductors 422 and 426 may be connected to a power line and a control circuit (or a logic circuit) described later, and the at least one ground conductors 423 and 427 may be connected to the ground 470 formed in the second substrate 410, as illustrated in FIG. 4B. Unlike the at least one ground conductors 423 and 427, the floating conductors 422 and 426 may not be electrically connected to the ground 470, like a conductor 422 in FIG. 4B. The floating conductor 422 and at least ground conductor 423, disposed on the upper surface, may be electrically connected to each other by the fastening member (e.g., the screw) 510 inserted through the fastening structure as described later, and a floating conductor 426 and at least on ground conductor 427 may be electrically connected to each other by contact between the electronic device 202 and the ground pad 371 of the first substrate 310 as described later.

The antenna connector 440 provided in the communication device 201 may be implemented as in a well-known technology, and thus a detailed description thereof will be omitted.

According to various embodiments, the contactor 450 may include an element (e.g., multiple pins) to be electrically connected to the connector 503 of the slot 360 of the electronic device 202. As described later, in the state in which the communication device 201 is inserted into the slot 360 of the electronic device 202, the contactor 450 may be brought into contact with and/or connected to the connector 503 of the slot 360, and thus an electrical element (e.g., a power line or a signal line) of the communication device 201 may be connected to an electrical element (e.g., a power line or a signal ling) of the electronic device 202 so that power, signals, data, and/or information may be exchanged between the elements (e.g., the processor (e.g., 610 in FIG. 6 described later) of the electronic device 202 and a second converter circuit (e.g., 680 in FIG. 6 described later) of the communication device 201. The contactor 450 provided in the communication device 201 may be implemented as in a well-known technology, and thus a detailed description thereof will be omitted.

Without being limited to the description, contents described below may be applied to various types of devices (e.g., a memory card and a graphic card), which can be inserted into the electronic device 202, in addition to the communication device 201.

Hereinafter, a description will be made of one example of fastening between the communication device 201 and the electronic device 202 according to various embodiments.

FIG. 5 is a view illustrating an example of fastening between a communication device and an electronic device according to various embodiments.

Referring to FIG. 5, the slot 360 of the electronic device 202 may include, as illustrated in FIG. 5, a structure 501 including a connector 503 which is to be electrically connected to the contactor 450 of the communication device 201. The connector 503 may include multiple pins for electrical connection, and may be electrically connected to the communication device 201 by being brought into contact and/or connected to the multiple pins included in the contactor 450 of the communication device 201.

According to various embodiments, in a state in which a portion (e.g., the contactor 450) of the communication device 201 is inserted into the slot 360 (e.g., the structure 501 of the slot 360) of the electronic device 202, the first substrate 310 of the electronic device 202 may be fastened to the second substrate 410 of the communication device 201. In a state in which the second substrate 410 of the communication device 201 is inserted into the structure 501 of the slot 360, a fastening member 510 (e.g., a screw), or members for fastening without being limited to the description) is fastened, as illustrated in FIG. 5, to the fastening structure of the first substrate 310 of the electronic device 202 through the recessed region 411 of the fastening structure of the second substrate 410 of the communication device 201, and thus the second substrate 410 of the communication device 201 may be connected the first substrate 310 of the electronic device 202. The fastening member 510 may include a head 511 and a body 513 having a screw line formed on the outer circumferential surface thereof Each of the head 511 and the body 513 may be formed of a material having conductivity, and thus may have conductivity. When the fastening member 510 is inserted into the fastening structure (e.g., a hole (372 in FIG. 3)) of the electronic device 202, the screw line formed on the outer circumferential surface of the body of the fastening member 510 may be engaged with a screw line in the fastening structure (e.g., a hole (372 in FIG. 3)) of the first substrate 310 of the electronic device 202. Due to the engagement, force is applied from the upper surface of the second substrate 410 of the communication device 201 toward the upper surface of the first substrate 310 of the electronic device 202 by the head 511 of the fastening member 510, and the second substrate 410 of the communication device 201 may be tightly fastened to the first substrate 310 of the electronic device 202.

According to various embodiments, when the second substrate 410 of the communication device 201 is completely fastened to the first substrate 310 of the electronic device 202 by the fastening member 510, electrically disconnected conductors disposed on at least one of the upper surface or the lower surface of the second substrate 410 of the communication device 201 may be electrically connected to each other. For example, the upper-surface ground pads 421 of the second substrate 410 of the communication device 201, described above, may be brought into contact with a portion of the head 511 (e.g., the bottom surface of the head 511) of the fastening member 510, and the upper-surface ground pads 421 may be electrically connected to each other through the head 511 of the fastening member 510. In another example, the lower-surface ground pads 425 of the second substrate 410 of the communication device 201 may be brought into contact with the ground pad 371 formed at the fastening structure of the upper surface of the first substrate 310 of the electronic device 202, and the lower-surface ground pads 425 may be electrically connected to each other through the ground pad 371 of the first substrate 310 of the electronic device 202. Thus, a ground (e.g., 641 in FIG. 6 described later) of the electronic device 202 may be electrically connected to the ground 470 of the communication device 201 through the ground pad 371 of the first substrate 310 and the lower-surface ground pads 425 of the second substrate 410, and thus a ground of the communication device 201 may be ensured. For example, the ground of the electronic device 101 may be used as a ground while an operation of the communication device 201 is performed. A control circuit 690, described later, may detect at least one of whether the upper-surface ground pads 421 are electrically connected to each other or whether the lower-surface ground pads 425 are electrically connected to each other, and a description thereof will be made later in FIGS. 7A to 7D, 8, 9, 10A, and 10B.

Hereinafter, a description will be made of examples of circuit configurations of the electronic device 202 and the communication device 201 electrically and/or operatively connected by the above-described insertion and fastening.

Hereinafter, a description will be made of an example of electrical connection and/or operative connection between electronic device 202 and communication device 201 by the insertion and/or fastening of the communication device 201.

According to various embodiments, by insertion of the communication device 201 into the electronic device 202 (e.g., the contactor 450 of the communication device 201 is brought into contact with a connector 503 of the electronic device 202) and fastening between the electronic device 202 and the electronic device 202, as illustrated in FIG. 6, the electronic device 202 may be electrically connected to some circuit elements of the communication device 201.

For example, lines (or lanes) (e.g., (a power lane, a power rail, or a power line), a bus line, a control signal line) for exchanging power, signals, information and/or data between the electronic device 202 and the communication device 201 may be connected to each other. In one example, a first converter circuit 634 of the electronic device 202 may be connected to a second converter circuit 680 of the communication device 201 through power lines. A first power line connected to an output terminal of the first converter circuit 634 may be electrically connected to a second power line connected to an input terminal of the second converter circuit 680. In another example, a signal line for transmitting and/or receiving a control signal may be connected to a bus line for transmitting and/or receiving data. A signal line connected to a first processor 610 of the electronic device 202 may be electrically connected to a signal line connected to a second processor 650 of the communication device 201. Further, the signal line of the first processor 610 of the electronic device 202 may be electrically connected to signal lines of other elements (e.g., the second converter circuit 680) of the communication device 201.

In another example, the ground 641 of the electronic device 202 may be connected to a ground 642 of the communication device 201 (e.g., the ground 470 formed in the second substrate 410 in FIG. 4B). As described above, the ground pad 371 of the fastening structure of the first substrate 310 of the electronic device 202 is connected to the lower-surface ground pads 425 of the second substrate 410 of the communication device 201, and thus the ground 641 of the electronic device 202 and the ground 642 of the communication device 201 may be electrically connected to each other as illustrated in FIG. 6. The grounds (e.g., 641) of the electronic device 202 is electrically connected to the grounds 642 of the communication device 201, and thus grounds for the elements of the communication device 201 may be ensured.

Hereinafter, a description will be made of an example of the circuit configuration of the electronic device 202 and an example of the circuit configuration of the communication device 201.

First, an example of the circuit configuration of the electronic device 202 will be described.

According to various embodiments, referring to FIG. 6, the electronic device 202 may include a first processor 610, a communication module 620, interface circuits 621, 622, and 623 for connection to multiple devices (e.g., a speaker, a display, and an input device, such as a mouse and a keyboard), multiple memories 631, 632, and 633, a first converter circuit 634, and a ground 641.

According to various embodiments, the first processor 610 of the electronic device 202 may transmit a control signal to elements (e.g., the second converter circuit 680) of the communication device 201 electrically connected thereto. The first processor 610 is not limited to that illustrated in FIG. 6, and may transmit a control signal to other elements (e.g., the second processor 650 of the communication device 201) in addition to the second converter circuit 680 of the communication device 201. Thus, the operation in which the first processor 610 transmits a control signal to the second converter circuit 680 of the communication device 201 may also be applied to an operation in which the first processor 610 transmits a control signal to other elements of the communication device 201 (e.g., the second processor 650 of the communication device 201). The first processor 610 may be implemented like the processor 320 in FIG. 3, and thus a redundant description will be omitted.

According to various embodiments, the communication module 620 may establish a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 202 and the external electronic device 202, and may support communication using the established communication channel. The communication module 620 may support a communication scheme that is different from a communication scheme supported by the communication device 201. For example, when the communication device 201 supports 5G communication, a communication module of the electronic device 202 may support network communication, such as a personal area network (PAN) or WAN. The communication module 620 may be implemented like the communication module 190 in FIG. 1, and thus a redundant description thereof will be omitted.

According to various embodiments, each of the interface circuits 621, 622, and 623 may include a connection element, such as a connector, to be connected to a speaker, a display, and input devices, such as a mouse and a keyboard.

In addition, the memories 631, 632, and 633 may be implemented as in a well-known technology, and thus a detailed description thereof will be omitted.

According to various embodiments, the first converter circuit 634 may be a converter circuit for converting DC power (e.g., increasing a voltage or reducing a voltage) and transmitting the same to other elements of the electronic device 202. For example, the first converter circuit 634 may convert power acquired from a battery (e.g., 330 in FIG. 3) and transmit the same to the other elements (e.g., the first processor 610) of the electronic device 202. In another example, the first converter circuit 634 may convert power and transmit the same to elements (e.g., the second converter circuit 680) of the communication device 201 which is electrically connected thereto. Without being limited to the description, the first converter circuit 634 may also transmit the converted power to other elements (e.g., the second processor 650 of the communication device 201) in addition to the second converter circuit 680 of the communication device 201. The first converter circuit 634 may be a DC/DC converter circuit which includes a voltage-reducing converter, a buck converter, a step-down converter, a voltage-increasing converter, a boost converter, a step-up converter, a voltage-increasing/reducing converter, a buck-boost converter, a negative voltage converter, a switching converter, or an inverting converter. Alternatively, without being limited to the description, the first converter circuit 634 may be a DC/AC converter circuit or an AC/DC converter circuit.

According to various embodiments, the ground 641 may be electrically connected to some of the circuit elements of the electronic device 202 to become a common ground when electrical operations of the circuit elements are performed. Referring to FIG. 6, as described above, the ground may be electrically connected to the ground pad 371 of the slot 360 disposed on the first substrate 310.

Hereinafter, an example of the circuit configuration of the communication device 201 will be described.

According to various embodiments, referring to FIG. 6, the communication device 201 may include the second processor 650, a transceiver 660, multiple memories 671 and 672, the second converter circuit 680, a control circuit 690, and the ground 642 (e.g., 740 in FIG. 4B).

According to various embodiments, the second processor 650 of the communication device 201 may control overall operations of the communication device 201. The second processor 650 of the communication device 201 may be implemented like the above-described first processor 610 of the electronic device 202, and thus a redundant description thereof will be omitted. The second processor 650 of the communication device 201 may be a modem processor.

According to various embodiments, the transceiver 660 may transmit and/or receive a communication signal based on a communication scheme supported by the communication device 201. The transceiver 660 may include multiple antennas. A description of the multiple antennas is as described above, and thus a redundant description thereof will be omitted.

According to various embodiments, the multiple memories 671 and 672 may include read-only memory (ROM) (ROM #1, 671) for storing an operating program (operating system (OS)) for driving the communication device 201, and random access Memory (RAM) 672 for storing data for hosting websites or data regarding programs or applications (for example, a web application), a full code, and/or state/context information. In addition, the memories 671 and 672 may be implemented as in a well-known technology, and thus a detailed description thereof will be omitted.

According to various embodiments, the second converter circuit 680 may convert DC power (e.g., may increase or reduce a voltage) and transmit the same to other elements of the communication device 201. For example, an input terminal of the second converter circuit 680 may be electrically connected to the first converter circuit 634 of the electronic device 202, and may convert power transferred from the first converter circuit 634 and transfer the same to other elements (e.g., the second processor 650) of the communication device 201. Like the first converter circuit 634, the second converter circuit 680 may be a DC/DC converter circuit. Alternatively, without being limited to the description, the second converter circuit 680 may also be a DC/AC converter circuit or an AC/DC converter circuit.

According to various embodiments, the control circuit 690 may be configured to output a control signal for controlling some elements (e.g., the second converter circuit 680) of the communication device 201. For example, the control signal may be a signal which induces the second converter circuit 680 to perform an operation of converting power provided from the electronic device 202 (e.g., power transferred from the first converter circuit 634) and transferring the power to the elements of the communication device 201. As illustrated in FIG. 6, the control circuit 690 may be electrically connected to some of a power line (e.g., a power line input into the second converter circuit 680), a signal line (e.g., a control signal line input into the second processor 650), some of ground pads (e.g., the above-described upper-surface ground pads 421 or lower-surface ground pads 425 in FIGS. 4A and 4B) (e.g., the floated ground pads (e.g., 422 and 426)), and some elements (e.g., the second converter circuit 680) of the communication device 201. It is illustrated that the control circuit 690 is connected to only the second converter circuit 680. However, the control circuit 690 is not limited thereto, and may be connected to various elements of the communication device 201 to transmit, to the various elements, control signals for controlling the various elements.

According to various embodiments, the control circuit 690 may output a control signal for controlling the second converter circuit 680 based on a signal (e.g., a high-level signal or a low-level signal) generated by at least one among a power line, a signal line, or some of the ground pads. A signal received by the control circuit 690 may include a high-level signal and a low-level signal. The high-level signal may be defined as a signal having a high value (e.g., +5V, Vcc), and the low-level signal may be defined as a signal having a low value (e.g., 0V, gnd). The high value and the low value are not limited to the description, can be configured as various values, and can also be adjusted. For example, the control circuit 690 may receive the high-level signal or the low-level signal generated based on whether there is electrical connection between the ground pads (e.g., the above-described upper-surface ground pads 421 or lower-surface ground pads 425 in FIGS. 4A and 4B), and may output, based on the received signal, a control signal for controlling a converter circuit. In one example, the control circuit 690 may receive a signal (e.g., a signal having a high value) when the upper-surface ground pads 421 (or the lower-surface ground pads 425) are electrically connected to each other, and may output a control signal, based on the received signal. In another example, the control circuit 690 may receive a signal (e.g., a signal having a low value) generated when the upper-surface pads 421 (or the lower-surface ground pads 425) are not electrically connected to each other, and may output the control signal, based on the received signal. A specific example of the control circuit 690 and examples of an operation thereof will be described below.

Hereinafter, specific examples of the control circuit 690 and examples of operation thereof will be described with reference to FIGS. 7A to 7D. Without being limited to the elements illustrated in FIGS. 7A to 7D, the control circuit 690 may be implemented so as to include more elements (e.g., electrical elements, such as an inductor, a capacitor, and a resistor) or fewer elements than the elements illustrated in FIGS. 7A to 7D. It is illustrated that an output terminal of the control circuit 690 (e.g., a logic circuit or a switch) is connected to the second converter circuit 680, but the output terminal of the control circuit 690 is not limited thereto, and may be connected to various elements of the communication device 201.

According to various embodiments, as illustrated in FIG. 7A, the control circuit 690 may include an AND logic circuit 710 including two input terminals (e.g., a first input terminal and a second input terminal) and an output terminal, an inverter 714, and a resistor (e.g., a pull-up resistor) 713. The first input terminal of the AND logic circuit 710 may be connected to a signal line. The second input terminal of the AND logic circuit 710 may be connected to an output terminal of the inverter 714, and an input terminal of the inverter may be connected to a floated ground pad (e.g., a first conductor 422) among ground pads (e.g., the upper-surface ground pads 421 or the lower-surface ground pads 425 illustrated in FIGS. 4A and 4B), and may be connected to a power line 712 through the resistor 713. The first input terminal of the AND logic circuit 710 may receive, through the signal line 711, a first signal (e.g., a signal for turning on a converter) which is a high-level signal output from the first processor 610 of the electronic device 202. The second input terminal of the AND logic circuit 710 may receive a second signal, which is a high-level signal, or a third signal, which is a low-level signal, from the output terminal of the inverter 714 based on whether the floated ground pad (e.g., the first conductor 422) is electrically connected to the remaining ground pads (e.g., at least one second conductor 423). The operation of receiving signals having different levels (e.g., a high level or a low level) based on whether the ground pad is electrically connected will be described later in relation to FIGS. 8, 9, 10A, and 10B. When high-level signals are received through both the first input terminal and the second input terminal, the AND logic circuit 710 may output, through the output terminal thereof, a control signal for controlling the second converter circuit 680.

According to various embodiments, as illustrated in FIG. 7B, the control circuit 690 may include an AND logic circuit 720 including three input terminals (e.g., a first input terminal, a second input terminal, and a third input terminal) and an output terminal, inverters (e.g., a first inverter 725 and a second inverter 726), and resistors (e.g., a first resistor 723 and a second resistor 724). The first input terminal of the AND logic circuit 720 may be connected to a signal line 722. The first input terminal of the AND logic circuit 720 may receive, through the signal line, a first signal (e.g., a signal for turning on the second converter circuit 680), which is a high-level signal output from the first processor 610 of the electronic device 202. The second input terminal of the AND logic circuit 720 may be connected to an output terminal of the first inverter 725, and an input terminal of the first inverter may be connected to a floated ground pad (e.g., the first conductor 422) among upper-surface ground pads, and may be connected to a power line 721 through the first resistor 723. The second input terminal of the AND logic circuit 720 may receive a second signal, which is a high-level signal, or a third signal, which is a low-level signal, from an output terminal of the first inverter 725 based on the floated ground pad (e.g., the first conductor 422) is electrically connected to the remaining ground pads (e.g., the at least one second conductor 423). The third input terminal of the AND logic circuit 720 may be connected to an output terminal of the second inverter 726, and an input terminal of the second inverter 726 may be connected to a floated ground pad (e.g., a third conductor 426) among lower-surface ground pads, and may be connected to the power line 721 through the second resistor 724. The third input terminal of the AND logic circuit 720 may receive a second signal, which is a high-level signal, or a third signal, which is a low-level signal from the output terminal of the second inverter 726 based on whether the floated ground pad (e.g., the third conductor 426) is electrically connected to the remaining ground pads (e.g., at least one fourth conductor 427). The operation of receiving signals having different levels (e.g., a high level or a low level) based on whether the ground pad is electrically connected will be described later in relation to FIGS. 8, 9, 10A, and 10B. When high-level signals are received through all of the first input terminal, the second input terminal, and the third input terminal, the AND logic circuit 720 may output, through the output terminal thereof, a control signal for controlling the second converter circuit 680.

According to various embodiments, as illustrated in FIG. 7C, the control circuit 690 may include an NOR logic circuit 730 including three input terminals (e.g., a first input terminal, a second input terminal, and a third input terminal) and an output terminal, and resistors (e.g., a first resistor 733 and a second resistor 734). The first input terminal of the NOR logic circuit 730 may be connected to a signal line 732. The first input terminal of the NOR logic circuit 730 may receive, through the signal line 732, a first signal (e.g., a signal for turning on the second converter circuit 680), which is a high-level signal output from the first processor 610 of the electronic device 202. The second input terminal of the NOR logic circuit 730 may be connected to a floated ground pad (e.g., the first conductor 422) among upper-surface ground pads, and may be connected to a power line 731 through the first resistor 733. The second input terminal of the NOR logic circuit 730 may receive a second signal, which is a high-level signal, or a third signal, which is a low-level signal, based on whether the floated ground pad (e.g., the first conductor 422) is electrically connected to the remaining ground pads (e.g., the at least one second conductor 423). The third input terminal of the NOR logic circuit 730 may be connected to a floated ground pad (e.g., the third conductor 426) among lower-surface ground pads, and may be connected to the power line 731 through the second resistor 734. The third input terminal of the NOR logic circuit 730 may receive a second signal, which is a high-level signal, or a third signal, which is a low-level signal, based on whether the floated ground pad (e.g., the third conductor 426) is electrically connected to the remaining ground pads (e.g., the at least one fourth conductor 427). The operation of receiving signals having different levels (e.g., a high level or a low level) based on whether the ground pad is electrically connected will be described later in relation to FIGS. 8, 9, 10A, and 10B. When a low-level signal is received through the first input terminal, and when high-level signals are received through all of at least one of the second input terminal or the third input terminal, the NOR logic circuit 730 may output, through the output terminal thereof, a control signal for controlling the second converter circuit 680.

According to various embodiments, as illustrated in FIG. 7D, the control circuit 690 may include a switch circuit 740 and resistors (e.g., a first resistor 743 and a second resistor 744). An input terminal of the switch circuit 740 may be connected to an output terminal of the first converter circuit 634 of the electronic device 202, and an output terminal of the switch circuit is connected to an input terminal of the second converter circuit 680 of the communication device 201. Therefore, whether power is transferred from the first converter circuit 634 to the second converter circuit 680 may be determined based on the opened/closed state of the switch circuit 740. For example, the opened/closed state of the switch circuit may be changed depending on whether the upper-surface ground pads 422 and 423 are electrically connected to each other and whether the lower-surface ground pads 426 and 427 are electrically connected to each other. For example, a first signal input terminal of the switch circuit 740 may be connected to a floated ground pad (e.g., the first conductor 422) among the upper-surface ground pads, and may be connected to a power line 741 through the first resistor 743. The first signal input terminal of the switch circuit 740 may receive a high-level signal or a low-level signal based on whether the floated ground pad (e.g., the first conductor 422) is electrically connected to the remaining ground pads (e.g., at least one second conductor 423). A second signal input terminal of the switch circuit 740 may be connected to a floated ground pad (e.g., the third conductor 426) among the lower-surface grounds, and may be connected to the power line 741 through the second resistor 744. The first signal input terminal of the switch circuit 740 may receive a high-level signal or a low-level signal based on whether the floated ground pad (e.g., the third conductor 426) is electrically connected to the remaining ground pads (e.g., the at least one fourth conductor 427). The switch circuit 740 may be implemented such that, when a high-level signal is received from two signal input terminals (e.g., the first signal input terminal and the second signal input terminal), the switch circuit 740 is closed, and thus poser is transferred from the first converter circuit 634 to the second converter circuit 680. Further, the switch circuit 740 may be implemented such that the switch circuit 740 is closed when a high-level signal is received from at least one of two signal input terminals. Further, the switch circuit 740 may be implemented such that the switch circuit 740 is opened when low-level signals are received from all of two signal input terminals. The second converter circuit 680 may be turned on by receiving a control signal from the first processor 610 through a signal line 742, and may convert and output power received while the switch circuit 740 is closed.

Hereinafter, examples of an operation of the communication device 201 according to various embodiments will be described.

According to various embodiments, the communication device 201 (e.g., the control circuit 690) may perform an operation of blocking a signal and/or power, received from the electronic device 202, based on whether the communication device 201 is fastened normally by the fastening member and/or whether the communication device 201 is brought into contact with the ground pad 371 of the first substrate 310 of the electronic device 202.

FIG. 8 is a flowchart 800 illustrating one example of an operation of a communication device according to various embodiments. According to various embodiments, operations illustrated in FIG. 8 may be performed in various orders without being limited to the illustrated order. Further, according to various embodiments, more operations than the operations illustrated in FIG. 8 may be performed, or at least one operation which is fewer than the operations illustrated in FIG. 8 may be performed. Hereinafter, FIG. 8 will be described with reference to FIGS. 9, 10A, and 10B.

FIG. 9 is a view illustrating one example of an operation of blocking a signal and/or power, which is received from an electronic device, on the basis of whether a communication device according to various embodiments is normally fastened by a fastening member of the communication device and/or whether the communication device is brought into contact with a ground pad of a first substrate of the electronic device. FIG. 10A is a view illustrating an example of electrical connection between upper-surface ground pads of a communication device according to various embodiments by a fastening member. FIG. 10B is a view illustrating an example of electrical connection between lower-surface ground pads of a communication device according to various embodiments by a ground pad of a first substrate of an electronic device.

According to various embodiments, in operation 801, the communication device 201 (e.g., a control circuit (e.g., 690 in FIG. 6)) may receive a first signal from a processor of an external electronic device 202. For example, as illustrated in FIG. 9, the control circuit (e.g., 690 in FIG. 6) (e.g., the AND logic circuit) may receive, through the first input terminal, a high-level signal (e.g., the first signal (e.g., a signal for turning on the second converter circuit 680)) or a low-level signal from the first processor 610 of the electronic device 202 via electrically connected signal lines 912 and 922. As described in FIG. 5, when the communication device 201 is completely inserted into the slot 360 of the electronic device 202 (e.g., a contact part of the communication device 201 is brought into contact with a connector of the electronic device 202), a second signal line 922 connected to the first input terminal of the control circuit (e.g., 690 in FIG. 6) of the communication device 201 may be connected to a first signal line 912 of the electronic device 202. When the first processor 610 of the electronic device 202 outputs a first signal (e.g., a signal for turning on the second converter circuit 680), the control circuit (e.g., 690 in FIG. 6) may receive, through the first input terminal, the first signal which is a high-level signal, and may receive a low-level signal (or may not receive a signal) when the first processor 610 does not output the first signal.

According to various embodiments, the first processor 610 of the electronic device 202 may output the first signal (e.g., the signal for turning on the second converter circuit 680), based on satisfaction of a designated event. For example, the satisfaction of the designated event may include an event in which the electronic device 202 is turned on, or an event in which a program for controlling the electronic device 202 to output the first signal is executed and/or driven. Without being limited to the description, the first processor 610 of electronic device 202 may be configured to output the first signal in response to receiving a signal fed back from the communication device 201 (e.g., a signal indicting whether the communication device 201 is fastened and/or whether the communication device 201 is brought into contact with a ground pad of the first substrate of the electronic device 202). A description thereof will be described later in FIGS. 12 and 13.

According to various embodiments, in operation 802, when a first conductor is electrically connected to at least one second conductor, the communication device 201 may receive a second signal through the first conductor. For example, as illustrated in FIG. 9, the control circuit (e.g., 690 in FIG. 6) (e.g., the AND logic circuit 720) may receive a high-level signal (e.g., the second signal) or a low-level signal through the second input terminal based on whether upper-surface ground pads (e.g., the first conductor 422 and the at least one second conductor 423) disposed on the upper surface of the second substrate 410 of the communication device 201 are electrically connected to each other. The second input terminal of the AND logic circuit 720 may be connected, through the first inverter 725, to a ground pad (e.g., the first conductor 422), which is floated (or is not connected to the ground), among the upper ground pads, and may be connected to a power line (e.g., a second power line 921 connected to the input terminal of the second converter circuit 680) through the first resistor 723. The state of electrical connection between the upper-surface ground pads 422 and 423 may be changed depending on the communication device 201 is fastened to the electronic device 202 by a fastening member (e.g., a screw) (e.g., 510), and a high-level signal or a low-level signal may be generated based on the change of the connection state. The second input terminal of the AND logic circuit 720 may receive the high-level signal or the low-level signal that has been generated based on the change of the connection state. Hereinafter, a description will be additionally made of a change in the state of electrical connection between the upper-surface ground pads 422 and 423 and an example of an operation of receiving a high-level signal or a low-level signal by the AND logic circuit 720 based on the change in the state of electrical connection.

According to various embodiments, when the upper-surface ground pads are electrically disconnected from each other, the AND logic circuit 720 may receive a low-level signal (e.g., a signal having a designated low value). For example, as illustrated in 1001 of FIG. 10A, upper-surface ground pads (e.g., the first conductor 422 and the at least one second conductor 423 electrically disconnected the first conductor 422) disposed to be spaced apart from each other on the upper surface of the second substrate 410 of the communication device 201 may be electrically disconnected from each other. When the first converter circuit 634 outputs power, power flowing along the second power line 921 due to the electrical connection drops to a high-level signal (e.g., a signal having a designated high value (e.g., Vcc, +5V)) through the first resistor 723 (e.g., a voltage and/or a current is dropped by a resistor), and the high-level signal may be transferred to an input terminal of the first inverter 725 through the first conductor 422 connected to the first resistor 723. The first inverter 725 may invert the high-level signal into a low-level signal, and may output the low-level signal through an output terminal. The AND logic circuit 720 may receive, through the second input terminal, the low-level signal output from the first inverter 725.

According to various embodiments, when the upper-surface ground pads 422 and 423 are electrically connected to each other, the AND logic circuit 720 may receive a high-level signal (e.g., a signal having a designated high value). For example, as illustrated in 1002 of FIG. 10A, in a state in which the second substrate 410 of the communication device 201 is completely inserted into the slot 360 of the electronic device 202, the fastening member 510 may be inserted into, the fastening structure of the electronic device 202 through a recessed region (e.g., 411) of the fastening structure of the second substrate 410 of the communication device 201. When the fastening member 510 is completely fastened, the head 511 of the fastening member 510 may be brought into contact with all of the upper-surface ground pads (e.g., the first conductor 422 and the at least one second conductor 423 electrically disconnected from the first conductor 422), which are electrically disconnected from each other. The upper-surface ground pads may be electrically connected to each other through the head 511 of the contacted fastening member 510. As described above, in a state in which the communication device 201 and the electronic device 202 are electrically connected to each other (e.g., the contactor 450 of the communication device 201 is brought into contact with the connector 503 of the electronic device 202), when the first converter circuit 634 outputs power, power flowing along the second power line 921 due to the electrical connection drops to a high-level signal (e.g., a signal having a designated high value (e.g., Vcc, +5V)) through the first resistor 723 (e.g., a voltage and/or a current is dropped by a resistor), and the high-level signal may be transferred to the first conductor 42. The dropped high-level signal transferred to the first conductor 422 may be emitted to a ground through the at least one second conductor 423 electrically connected the first conductor 422 through the head 511 of the fastening member 510. When the high-level signal is emitted, a low-level signal may be transferred from the first conductor 422 to an input terminal of the first inverter 725. The first inverter 725 may invert the input low-level signal into a high-level signal, and may output the high-level signal through an output terminal thereof The AND logic circuit 720 may receive, through the second input terminal, the high-level signal output from the first inverter 725.

When the communication device 201 and the electronic device 202 are not electrically connected to each other, power (or a high-level signal) is not applied to the first conductor 422, and thus the first conductor 422 may be in a floating state. In this case, there is no signal which is applied to the input terminal of the first inverter, and thus there may be also no signal which is output from the output terminal the first inverter 725. In other words, when the communication device 201 is not electrically connected to the electronic device 202, there may be no signal applied to the second input terminal of the AND logic circuit 720.

According to various embodiments, in operation 803, when the third conductor 426 is electrically connected to the at least one fourth conductor 427, the communication device 201 may receive a third signal through the third conductor 426. For example, as illustrated in FIG. 9, the control circuit (e.g., 690 in FIG. 6) (e.g., the AND logic circuit 720) may receive, through a third input terminal, a high-level signal (e.g., the third signal) or a low-level signal based on whether lower-surface ground pads (e.g., the third conductor 426 and the at least one fourth conductor 427) disposed on the lower surface of the second substrate 410 of the communication device 201 are electrically connected to each other. The third input terminal of the AND logic circuit 720 may be connected, through the inverter 726, to a ground pad (e.g., the third conductor 426), which is floated (or is not connected to the ground), among lower-surface ground pads, and may be connected to a power line (e.g., a second power line connected to the input terminal of the second converter circuit 680) through a second resistor. The state of electrical connection between the lower-surface ground pads 426 and 427 may be changed depending on whether the lower-surface ground pads 426 and 427 of the second substrate 410 of the communication device 201 is brought into contact with a ground pad on the first substrate of the electronic device 202, and a high-level signal or a low-level signal may be generated based on the change in the connection state. The third input terminal of the AND logic circuit 720 may receive the high-level signal or the low-level signal generated based on the change in the electrical connection state. Hereinafter, a description will be further made of a change in electrical connection the lower-surface ground pads 426 and 427 and an example of an operation of receiving a high-level signal or a low-level signal by the AND logic circuit 720 based on the change in the electrical connection state.

According to various embodiments, when the lower-surface ground pads are electrically disconnected from each other, the AND logic circuit 720 may receive a low-level signal (e.g., a signal having a designated low value). For example, as illustrated in 1011 of FIG. 10B, lower-surface ground pads (e.g., the third conductor 426 and the at least one fourth conductor 427 electrically disconnected from the third conductor 426) disposed while being spaced apart from each other on the lower surface of the second substrate 410 of the communication device 201 may be electrically disconnected from each other. When the communication device 201 is completely inserted into the electronic device 202, the first converter circuit 634 of the electronic device 202 and the second converter circuit 680 of the communication device 201 may be electrically connected to each other. When the first converter circuit 634 outputs power, power flowing along the second power line 921 due to the electrical connection drops to a high-level signal (e.g., a signal having a designated high value (e.g., Vcc, +5V)) through the second resistor 724 (e.g., a voltage and/or a current is dropped by a resistor), and the high-level signal may be transferred to an input terminal of the second inverter through the third conductor 426 connected to the second resistor 724. The second inverter 726 may invert the high-level signal into a low-level signal, and may output the low-level signal through an output terminal. The AND logic circuit 720 may receive, through the third input terminal, the low-level signal that has been output from the second inverter 726.

According to various embodiments, when the lower-surface ground pads 426 and 427 are electrically connected to each other, the AND logic circuit 720 may receive a high-level signal (e.g., a signal having a designated high value). For example, as illustrated in 1012 of FIG. 10B, the above-described state in which the second substrate 410 of the communication device 201 is completely inserted into the slot 360 of the electronic device 202, the fastening member 510 may be inserted into the fastening structure of the electronic device 202 through the recessed region of the fastening structure of the second substrate 410 of the communication device 201. Due to the inserted fastening member 510, force is applied from the upper surface of the first substrate 310 of the electronic device 202 toward the second substrate 410 of the communication device 201, and thus the lower surface of the second substrate 410 may be brought into close contact with the upper surface of the first substrate 310. Due to the close contact, the ground pad 371 of the first substrate 310 may be brought into contact with all of the lower-surface ground pads (e.g., the first conductor 422 and the first conductor 422 and the at least one second conductor 423 electrically disconnected from the first conductor 422) of the second substrate 410, which are electrically disconnected from each other. The lower-surface ground pads may be electrically connected to each other through the contacted ground pad 371 of the first substrate 310. As described above, in the state in which the communication device 201 is electrically connected to the electronic device 202 (e.g., the contactor 450 of the communication device 201 is in contact with the connector 503 of the electronic device 202), when the first converter circuit 634 outputs power, power flowing along the second power line 921 due to the electrical connection drops to a high-level signal (e.g., a signal having a designated high value (e.g., Vcc, +5V)) through the second resistor 724 (e.g., a voltage and/or a current is dropped by a resistor), and the high-level signal may be transferred to the third conductor 426. The dropped high-level signal transferred to the second conductor 423 may be emitted to a ground through the at least one fourth conductor 427 electrically connected to the third conductor 426 through a ground pad of the first substrate. When the high-level signal is emitted, a low-level signal may be transferred from the third conductor 426 to the input terminal of the second inverter 726. The second inverter 726 may invert the input low-level signal into a high-level signal, and may output the high-level signal through an output terminal. The AND logic circuit 720 may receive, through the third input terminal, the high-level signal that has been output from the second inverter 726.

When the communication device 201 is not electrically connected to the electronic device 202, like the first conductor 422, power (or a high-level signal) is not applied to the third conductor 426, and thus the third conductor 426 may be in a floating state. In other words, when the communication device 201 is not electrically connected to the electronic device 202, there may be no signal that is applied to the third input terminal of the AND logic circuit 720.

According to various embodiments, in operation 804, the communication device 201 may output, based on the first signal, the second signal, and the third signal, a control signal for controlling a converter. For example, as illustrated in FIG. 9, the AND logic circuit 720 may output a high-level signal (or a control signal) in response to receiving high-level signals through all input terminals (e.g., the first input terminal, the second input terminal, and the third input terminal). The high-level signal output from the AND logic circuit 720 may be configured to induce the second converter circuit 680 of the communication device 201 to perform an operation. The second converter circuit 680 may be driven in response to receiving of the control signal, and the driven second converter circuit 680 may convert power received, through the second power line 921, from a power line 911 connected to the output terminal of the first converter circuit 634, and may provide the converted power to other devices (e.g., the second processor 650) of the communication device 201. The other devices of the communication device 201 may be driven in response to being provided with the power to perform an operation.

Without being limited to the description, the communication device 201 may include various other types of devices, in place of the second converter circuit 680, for distributing power and providing the power to the remaining elements of the communication device 201. Like the second converter circuit 680, the devices are driven based on a control signal received from the control circuit (e.g., 690 in FIG. 6) (e.g., the AND logic circuit 720), and depending on the driving, may distribute, to the remaining elements of the communication device 201, power received from the electronic device 202 as it is or with conversion of the power.

Hereinafter, a description will be made of examples of an operation of the communication device 201 according to various embodiments.

According to various embodiments, the communication device 201 (e.g., the control circuit 690) may transmit, to the electronic device 202, a feedback signal indicating whether the communication device 201 is fastened by the fastening member and/or whether the lower surface of the second substrate 410 of the communication device 201 is brought into contact with the ground pad 371 of the first substrate 310 of the electronic device 202. The electronic device 202 may transmit a control signal or power to the communication device 201 based on the received feedback signal.

FIG. 11 is a flowchart 1100 illustrating one example of an operation of a communication device according to various embodiments. According to various embodiments, the operations illustrated in FIG. 11 may be performed in various orders without being limited to the illustrated order. Further, according to various embodiments, more operations than the operations illustrated in FIG. 11 may be performed, or at least one operation that is fewer than the operations illustrated in FIG. 11 may be performed. Hereinafter, FIG. 11 will be described with reference to FIG. 12.

FIG. 12 is a view illustrating one example of an operation of transmitting a feedback signal based on whether a communication device various embodiments is fastened and/or whether the communication device is brought into contact with a ground pad of a first substrate of an electronic device, and receiving a control signal from the electronic device.

According to various embodiments, in operation 1101, when the first conductor 422 is electrically connected to the at least one second conductor 423, and when the third conductor 426 is electrically connected to at least one fourth conductor 427, the communication device 201 may transmit a fastening sensing signal to the external electronic device 202. For example, as illustrated in FIG. 12, the communication device 201 may further include a first control circuit (e.g., 1200) (e.g., the AND logic circuit) for outputting a signal based on whether the communication device 201 is fastened by the fastening member and whether the lower surface of the second substrate 410 of the communication device 201 is brought into contact with a ground pad of the first substrate 310 of the electronic device 202. One input terminal (e.g., a fourth input terminal) of two input terminals (e.g., the fourth input terminal and a fifth input terminal) of the first control circuit (e.g., 1200) may be connected to an inverter 1201 connected to a ground pad (e.g., the first conductor 422), which is not connected to a ground, among upper-surface ground pads, the other input terminal (e.g., the fifth input terminal) may be connected to an inverter 1202 connected to a ground pad (e.g., the third conductor 426), which is not connected to the ground, among lower-surface ground pads.

According to various embodiments, when the upper-surface ground pads 422 and 423 are electrically connected to each other and when the lower-surface ground pads 426 and 427 are electrically connected to each other, the first control circuit 1200 may receive a high-level signal through the two input terminals, and may transmit, based on the reception of the high-level signal, a control signal to the first processor 610 of the electronic device 202. When the communication device 201 is electrically connected to the electronic device 202 (e.g., the contactor of the communication device 201 is brought into contact with the connector of the electronic device 202), the first control circuit 1200 may be electrically connected to the first processor 610 of the electronic device 202. For example, a signal line connected to an output terminal of the first control circuit 1200 may be electrically connected to a signal line connected to the input terminal of the first processor 610 of the electronic device 202. As described above, when the upper-surface and lower-surface ground pads are electrically connected, a low-level signal may be generated in floated ground pads (e.g., the first conductor 422 and third conductor 426). Each of the inverters (e.g., 1201 and 1202) may convert the low-level signal into a high-level signal, and may transmit the high-level signal to the input terminals (e.g., the fourth input terminal and the fifth input terminal) of the first control circuit 1200. The first control circuit 1200 may output a control signal in response to the reception of the high-level signal through the input terminals. For example, the control signal may indicate that the communication device 201 is fastened by the fastening member 510 and that the lower surface of the second substrate 410 of the communication device 201 is brought into contact with the ground pad 371 of the first substrate 310 of the electronic device 202.

According to various embodiments, in operation 1102, the communication device 201 (e.g., the control circuit) may receive a first signal from the first processor 610 of the external electronic device 202 in response to transmitting the signal. For example, the first processor 610 of the electronic device 202 may output, in response to receiving the control signal from the first control circuit 1200, a control signal for turning on the second converter circuit 680. As described in relation to FIGS. 8, 9, 10A, and 10B, the control circuit 720 may receive the control signal through the first input terminal. An operation of receiving a signal by the control circuit 720 through the first input terminal may be performed like the above-described operation 801 of the communication device 201, and thus a redundant description thereof will be omitted. In another example, based on the reception of the first signal, the first processor 610 may transmit, to the first converter circuit 634, a control signal for controlling the first converter circuit 634 to transmit power to the second converter circuit 680.

According to various embodiments, in operation 1103, the communication device 201 (e.g., the control circuit) may receive a second signal through the first conductor 422 and a third signal through the third conductor 426, and, in operation 1104, may output, based on the first signal, the second signal, and the third signal, a control signal for controlling a converter. For example, the control circuit 720 may receive a high-level signal (e.g., the second signal) through the second input terminal when the upper-surface ground pads (e.g., the first conductor 422 and the at least one second conductor 423) are electrically connected to each other, and may receive a high-level signal (e.g., the third signal) through the third input terminal when the lower-surface ground pads (e.g., the third conductor 426 and the at least one fourth conductor 427) are electrically connected to each other. The operation of receiving signals through the second input terminal and the third input terminal of the control circuit 720 may be performed like the above-described operations 802 and 803 of the communication device 201, and thus a redundant description thereof will be omitted. The control circuit 720 may output, in response to the reception of the high-level signals through all of the input terminals (e.g., the first input terminal, the second input terminal, and the third input terminal), a control signal for controlling (and/or driving) the second converter circuit 680. The operation of outputting the control signal by the control circuit 720 may be performed like the above-described operation 804 of the communication device 201, and thus a redundant description thereof will be omitted.

Hereinafter, a description will be made of examples of operations of various types of electronic devices according to various embodiments.

According to various embodiments, as described above, the above-described matters (e.g., electrical disconnection between ground pads, and the control circuit 690 (e.g., the AND logic circuit 720)) may be applied to various types of devices (e.g., a memory card and a graphic card), which can be inserted into the electronic device 202, in addition to the communication device 201.

Further, according to various embodiments, multiple fastening structures may be formed on a substrate of each of the devices (e.g., a memory card and a graphic card), and ground pads electrically disconnected from each other may be disposed in a region adjacent to the multiple fastening structures. As described above, some of the disconnected ground pads may not be connected to a ground, and the other ground pads may be connected to the ground. A control circuit of the device may be connected to some of the ground pads so as to receive a signal and perform an operation, based on whether the substrate is fastened and/or whether the substrate is brought into contact with the ground pad 371 on the first substrate 310 of the electronic device 202.

FIG. 13 is a flowchart 1300 illustrating one example of an operation of a device according to various embodiments. According to various embodiments, the operations illustrated in FIG. 13 may be performed in various orders without being limited to the illustrated order. Further, according to various embodiments, more operations than the operations illustrated in FIG. 13 may be performed, or at least one operation that is fewer than the operations illustrated in FIG. 13 may be performed. Hereinafter, FIG. 13 will be described with reference to FIG. 14.

FIG. 14 is a view illustrating one example of an operation of transmitting a feedback signal based on whether a device according to various embodiments is fastened and/or whether the device is brought into contact with a ground pad of a first substrate of an electronic device, and receiving a control signal from the device.

According to various embodiments, in operation 1301, a first device (e.g., a memory card or a graphic card) may receive a first signal from a processor of an external electrical device. For example, when the first device (e.g., a memory card or a graphic card) is inserted into the electronic device 202 (e.g., Note PC), the first device may be electrically connected to the electronic device 202. For example, as illustrated in FIG. 14, one input terminal (e.g., the first input terminal) of multiple input terminals of a control circuit of the first device may be electrically connected to the first processor 610 of the electronic device 202. A first input terminal of a control circuit 1410 (e.g., the AND logic circuit) may receive a control signal that is output from the first processor 610. The operation of receiving the first signal may be performed like the above-described operation 801 and operations 1101 and 1102 of the communication device 201, and thus a redundant description thereof will be omitted.

According to various embodiments, in operation 1302, the device (e.g., a memory card or a graphic card) may receive multiple signals from multiple conductors based on fastening of a fastening member. For example, the other input terminals of the multiple input terminals of the control circuit 1410 of the first device may be electrically connected to some ground pads, which are not connected to a ground, among ground pads 1401, 1402, 1403, and 1404 which are disposed in a region adjacent to multiple fastening structures of a substrate 1400 of the first device. As illustrated in relation to FIGS. 8, 9, 10A, and 10B, the electrical connection may be performed by the head of the fastening member in the case of upper-surface ground pads, and may be performed by a ground pad of the first substrate of the electronic device 202 in the case of lower-surface ground pads, and thus a redundant description thereof will be omitted. The some ground pads which are not connected to the ground may be connected to a power line, and may receive a high-level signal that has been dropped by a resistor. When the ground pads 1401, 1402, 1403, and 1404 are electrically connected to each other, a high-level signal may be emitted through other ground pads which are connected to the ground, and each of inverters connected to the other input terminals of the control circuit 1410 may convert a low-level signal, generated based on the emission of the high-level signal, into a high-level signal. Each of the input terminals of the control circuit 1410 may receive the high-level signal converted by each of the inverters. The operation of receiving a high-level signal or a low-level signal by the control circuit based on the ground pads 1401, 1402, 1403, and 1404 are electrically connected to each other may be as described in operations 802 and 803 of the communication device 201, and thus a redundant description thereof will be omitted.

According to various embodiments, in operation 1303, the device (e.g., a memory card or a graphic card) may output, based on the first signal and the multiple signals, a control signal for controlling a converter. For example, the above-described control circuit 1410 may output, in response to receiving a high-level signal through the multiple input terminals, a control signal for controlling a converter circuit 1420. The operation of outputting the control signal by the control circuit 1410 may be performed like the above-described operation 804 of the communication device 201, and thus a redundant description thereof will be omitted.

Hereinafter, examples of operations of various types of electronic devices according to various embodiments will be described.

According to various embodiments, the electronic device 202 may include a circuit for determining whether the above-described communication device 201 is fastened and/or whether the communication device 201 is fastened to the ground pad 370 of the first substrate 310 of the electronic device 202. When the circuit determines whether the above-described communication device 201 is fastened and/or whether the communication device 201 is fastened to the ground pad 371 of the first substrate 310 of the electronic device 202, the electronic device 202 may transmit a control signal (e.g., a converter circuit turn-on signal) and/or power to the communication device 201.

FIG. 15 is a flowchart 1500 illustrating one example of an operation of a device according to various embodiments. According to various embodiments, the operations illustrated in FIG. 15 may be performed in various orders without being limited to the illustrated order. Further, according to various embodiments, more operations than the operations illustrated in FIG. 15 may be performed, or at least one operation that is fewer than the operations illustrated in FIG. 15 may be performed. Hereinafter, FIG. 15 will be described with reference to FIGS. 16A and 16B.

FIG. 16A is a view illustrating one example of an operation of transmitting a control signal and/or power to a communication device, based on whether a ground pad of an electronic device, according to various embodiments is brought into contact with the communication device. FIG. 16B is a view illustrating one example of electrical connection between electrically disconnected ground pads of an electronic device according to various embodiments.

According to various embodiments, in operation 1501, the electronic device 202 may receive a first signal, based on insertion of the communication device 201. For example, referring to FIG. 16A, the first processor 610 of the electronic device 202 may receive a high-level signal based on whether ground pads 1601 and 1602, which are disposed to be spaced apart from each other on the first substrate 310 and are electrically disconnected from each other, are electrically connected to each other. One 1601, which is not connected to a ground, among the ground pads 1601 and 1602 may be connected to a power line through a resistor 1611, the other 1602 thereof may be connected to the ground 641. As illustrated in FIG. 16B, the ground pads 1601 and 1602, which are electrically disconnected from each other while being spaced apart from each other, are brought into contact with a lower-surface ground pad 1630 formed on the lower surface of the second substrate 410 of the communication device 201, and thus may be electrically connected to each other through the lower-surface ground pad. In this case, the high-level signal dropped by the resistor 1611 through the power line (e.g., a power line output from the first converter circuit 634) applied to one, which is not connected to the ground 1601, among the ground pads 1601 and 1602, may be emitted through the other 1602, which is connected to the ground, among the ground pads 1601 and 1602 according to the electrical connection. A low-level signal may be generated based on the emission of the high-level signal, and the generated low-level signal may be converted into a high-level signal by an inverter 1612, and transferred to the first processor 610.

As illustrated in FIG. 16B, the lower-surface ground pad 1630 of the second substrate 410 of the communication device 201 may be formed in an integrated type (or may be formed in an electrically unseparated type). Alternatively, the lower-surface ground pads (not shown) may be disposed to be electrically disconnected from each other, and the lower-surface ground pads may be implemented at a position corresponding to a spacing between the ground pads 1601 and the 1602 formed on the first substrate 310 so as to have a size that is larger than the size of the spacing. Thus, the ground pads 1601 and 1602 on the first substrate 310 of the electronic device 202 may be electrically connected to each other by the lower-surface ground pads spaced apart from each other. Further, although not illustrated, the above-described control circuit (e.g., the control circuit in FIG. 9) may also implemented in the communication device 201, and thus the first processor 610 may receive a signal based on not only whether the ground pads of the first substrate 310 are electrically connected to each other but also the ground pads (e.g., lower-surface ground pads and upper-surface ground pads) of the second substrate 410 of the communication device 201 are electrically connected to each other. For example, the first processor 610 may include two input terminals, and each of the two input terminals may be implemented so as to receive a high-level signal based on electrical connection between the ground pads disposed on the upper surface of the first substrate 310 and the lower surface of the second substrate 410.

According to various embodiments, in operation 1502, the electronic device 202 may transmit a control signal to the communication device 201 based on the reception of the first signal. For example, the first processor 610 may transmit, based on the reception of the first signal, a control signal for turning on the second converter circuit 680. In another example, the first processor 610 may transfer, based on the reception of the first signal, a control signal for controlling the first converter circuit 634 to transfer power to the second converter circuit 680 to the first converter circuit 634.

According to various embodiments, the communication device (e.g., 201 in FIG. 2) may be provided wherein the control circuit (e.g., 720 in FIG. 7B) is configured to refrain from outputting the control signal for controlling the converter circuit, based on receiving a third signal generated during electrical disconnection between the first conductor (e.g., 422 in FIG. 7B) and the at least one second conductor (e.g., 423 in FIG. 7B) while receiving the first signal through the signal line.

According to various embodiments, the communication device (e.g., 201 in FIG. 2) may be provided wherein, when the communication device (e.g., 201 in FIG. 2) is inserted into a slot of a substrate of the external electronic device (e.g., 202 in FIG. 2), the signal line is electrically connected to the processor of the external electronic device (e.g., 202 in FIG. 2), and the power line is electrically connected to a first converter circuit of the external electronic device (e.g., 202 in FIG. 2).

According to various embodiments, the communication device (e.g., 201 in FIG. 2) may be provided wherein the converter circuit is configured to convert, based on the reception of the control signal, power received through the power line and supply the converted power to other electrical components of the communication device (e.g., 201 in FIG. 2).

According to various embodiments, the communication device (e.g., 201 in FIG. 2) may be provided wherein the communication device (e.g., 201 in FIG. 2) is a communication device (e.g., 201 in FIG. 2) of an M.2 specification.

According to various embodiments, the communication device (e.g., 201 in FIG. 2) may be provided, and further includes a first substrate, wherein the first conductor (e.g., 422 in FIG. 7B) and the at least one second conductor (e.g., 423 in FIG. 7B) are disposed on the upper surface of the first substrate, wherein the first conductor and the at least one second conductor are spaced apart from each other, and a region recessed with a predetermined curvature inward from the side surface of the substrate is formed adjacent to the first conductor (e.g., 422 in FIG. 7B) and the at least one second conductor (e.g., 423 in FIG. 7B).
