Description

BACKGROUND

Field of the Disclosure

The disclosure relates generally to an information handling system, and in particular, a memory module socket for an information handling system.

Description of the Related Art

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

With DDR speeds approaching PCIe speeds, reflections become more important than ever. With the advent of equalization approaches like DFE (decision feedback equalization) both at memory controller and memory modules, the impact of loss is mitigated, but reflections are only mitigated to some extent.

SUMMARY

Innovative aspects of the subject matter described in this specification may be embodied in a memory module socket, including a first member extending between a first end and a second end of the socket, the second end of the socket opposite to the first end of the socket, the first member positioned along a first side of the socket, the first member including: a plurality of first contact pins, each of the first contact pins including a first contact point and a second contact point; a plurality of first resistive coatings connecting two or more of the first contact pins to define first groupings of contact pins; a plurality of first ribs separating each of the first groupings of first contact pins; wherein when the first contact pins are in a first position, the second contact points of the first contact pins are in contact with respective first resistive coatings to complete a termination to ground.

Other embodiments of these aspects include corresponding systems and apparatus.

These and other embodiments may each optionally include one or more of the following features. For instance, a second member extending between the first end and the second end of the socket, the second member positioned along a second side of the socket, the second side of the socket opposite to the first side of the socket, the second member including: a plurality of second contact pins, each of the second contact pins including a first contact point and a second contact point; a plurality of second resistive coatings connecting two or more of the second contact pins to define second groupings of contact pins; and a plurality of second ribs separating each of the second groupings of second contact pins. When the second contact pins are in the first position, the second contact points of the second contact pins are in contact with respective second resistive coatings to complete a termination to ground. When the first and the second contact pins are in the first position, a memory module is decoupled from the socket. When the first and the second contact pins are in a second position, the first contact points of the first and the second contact pins contact the memory module, and the second contact points of the first and the second contact pins are disconnected from termination. When the first and the second contact pins are in the second position, the memory module is coupled to the socket. A first contact pin of the first grouping of contact pins is a ground pin.

The first member 302 and the second member 304 can extend between a first end 306 and a second end 308 of the memory module socket 212. The first end 306 of the memory module socket 212 is opposite to the second end 308 of the memory module socket 212. The first member 302 is positioned along a first side 310 of the memory module socket 212. The second member 304 is positioned along a second side 312 of the memory module socket 212. The first side 310 of the memory module socket 212 is opposite to the second side 312 of the memory module socket 212. The memory module socket 212 can include a top side 250 positioned opposite to a bottom side 252.

Referring to FIGS. 3C and 4, the first member 302 can include a plurality of first contact pins 320a. Each of the first contact pins 320a can include a first contact point 322a and a second contact point 324a. The second member 304 can include a plurality of second contact pins 320b. The first contact pins 320a and the second contact pins 320b can collectively be referred to as contact pins 320.

The first contact points 322a, 322b can collectively be referred to as first contact points 322. The second contact points 324a, 324b can collectively be referred to as second contact points 324.

Referring to FIGS. 3C, 4, and 5, the first member 302 can include a plurality of first resistive coatings 328a. Each of the first resistive coatings 328a can connect two or more of the first contact pins 320a to define first groupings of the first contact pins 320a. In some examples, a particular first resistive coating 328a can connect two of the first contact pins 320a, defining a first grouping 330a of the first contact pins 320a. The first contact pins 320a of the first grouping 330a can include a ground pin and a data pin. In some examples, a particular first resistive coating 328a can connect three of the first contact pins 320a, defining a first grouping 330b of the first contact pins 320a. The first contact pins 320a of the first grouping 330b can include a ground pin, and two data pins.

Similarly, the second member 304 can include a plurality of second resistive coatings 328b. Each of the second resistive coatings can connect two or more of the second contact pins 320b to define first groupings of second contact pins 320a. In some examples, a particular second resistive coating 328b can connect two of the second contact pins 320b, defining a first grouping (not shown) of the second contact pins 320b. The second contact pins 320b of the first grouping (not shown) can include a ground pin and a data pin. In some examples, a particular second resistive coating 328b can connect three of the second contact pins 320b, defining a first grouping (not shown) of the second contact pins 320b. The second contact pins 320b of the first grouping (not shown) can include a ground pin, and two data pins.

Referring to FIGS. 3B and 3C, the first member 302 can include a plurality of first ribs 350a. The first ribs 330a can separate the first groupings 330a of the first contact pins 320a. The first ribs 350a can extend between the top side 250 and the bottom side 252 of the memory module socket 212, at least partially, or wholly. The first member 302 can include additional first ribs 352a. In some examples, the additional first ribs 352a can be positioned within first groupings 330a of the first contact pins 320a, and separate the first contact pins 320a within the first groupings 330a. In some examples, the first groupings 330a of the first contact pins 320a do not include the additional first ribs 352a. The additional first ribs 352a can extend between the top side 250 and the bottom side 252 of the memory module socket 212, at least partially, or wholly.

Similarly, the second member 304 can include a plurality of second ribs 350b. The second ribs 330b can separate the first groupings (not shown) of the second contact pins 320b. The second ribs 350b can extend between the top side 250 and the bottom side 252 of the memory module socket 212, at least partially, or wholly. The second member 304 can include additional second ribs 352b. In some examples, the additional second ribs 352b can be positioned within first groupings (not shown) of the second contact pins 320b, and separate the second contact pins 320b within the second groupings 330b. In some examples, the first groupings (not shown) of the second contact pins 320b do not include the additional second ribs 352b. The additional second ribs 352b can extend between the top side 250 and the bottom side 252 of the memory module socket 212, at least partially, or wholly.

The ribs 350a, 350b, 352a, 352b can minimize, reduce, and/or prevent, inadvertent contact between any of the first contact pins 320a and/or any of the second contact pins 320b. The ribs 350a, 350b, 352a, 352b can additionally help guide translation/movement of the first contact pins 320a and the second contact pins 320b from a first position to a second position, e.g., when the memory module 210 is coupled/engaged and decoupled/disengaged from the memory module socket 212, described further herein.

Referring back to FIGS. 4 and 5, the first contact pins 320a and the second contact pins 320b are in a first position. In some examples, when the first contact pins 320a and the second contact pins 320b are in the first position, the memory module 210 is decoupled/disengaged from the memory module socket 212. That is, the decoupling/disengagement of the memory module 210 from the memory module socket 212 places the first contact pins 320a and the second contact pins 320b in the first position.

When the first contact pins 320a are in the first position, the second contact points 324a are in contact with respective first resistive coatings 328a to complete a termination to ground. For example, the first contact pins 320a can include a natural spring force such that the second contact points 324a of the first contact pins 320a are in contact with respective first resistive coatings 328a when the memory module 210 is decoupled/disengaged from the memory module socket 212. In other words, when the memory module 210 is decoupled/disengaged from the memory module socket 212, the spring force of the first contact pins 320a can press the second contact points 324a against the respective first resistive coatings 328a and complete a signal-resistor-ground circuit.

Additionally, when the second contact pins 320b are in the first position, the second contact points 324b are in contact with respective second resistive coatings 328b to complete a termination to ground. For example, the second contact pins 320b can include a natural spring force such that the second contact points 324b of the second contact pins 320b are in contact with respective second resistive coatings 328b when the memory module 210 is decoupled/disengaged from the memory module socket 212. In other words, when the memory module 210 is decoupled/disengaged from the memory module socket 212, the spring force of the second contact pins 320b can press the second contact points 324b against the respective second resistive coatings 328b and complete a signal-resistor-ground circuit.

FIG. 6 illustrates the first contact pins 320a and the second contact pints 320b in a second position. In some examples, when the first contact pins 320a and the second contact pins 320b are in the second position, the memory module 210 is coupled/engaged with the memory module socket 212. That is, the coupling/engagement of the memory module 210 with the memory module socket 212 places the first contact pins 320b and the second contact pins 320b in the second position.

When the first contact pins 320a are in the second position, the first contact points 322a are in contact with the memory module 210. For example, the first contact pins 320a can include a natural spring force such that the first contact points 322a of the first contact pins 320a are in contact with the memory nodule 210 when the memory module 210 is coupled/engaged with the memory module socket 212. Furthermore, when the first contact pins 320a are in the second position, the second contact points 324a of the first contact pins 230a are not in contact with the respective first resistive coatings 328a and are disconnected from termination. In other words, when the memory module 210 is coupled/engaged with the memory module socket 212, the memory module 210 can prevent the second contact points 324a of the first contact pins 320a from contacting the respective first resistive coatings 328a and disconnected from ground termination.

Additionally, when the second contact pins 320b are in the second position, the second contact points 322b are in contact with the memory module 210. For example, the second contact pins 320b can include a natural spring force such that the second contact points 322b of the second contact pins 320b are in contact with the memory module 210 when the memory module 210 is coupled/engaged with the memory module socket 212. Furthermore, when the second contact pins 320b are in the second position, the second contact points 324b of the second contact pins 230b are not in contact with the respective second resistive coatings 328b and are disconnected from termination. In other words, when the memory module 210 is coupled/engaged with the memory module socket 212, the memory module 210 can prevent the second contact points 324b of the second contact pins 320b from contacting the respective second resistive coatings 328b and disconnected from ground termination.
