It is to be understood that other embodiments can be used and structural changes can be made without departing from the scope of the embodiments of this invention. As used herein, the terms “couple,” “connect,” and “attach” are interchangeable and include various forms of connecting one part to another either directly or indirectly. Also, it should be appreciated that one or more structural features described in one embodiment could be implemented in a different embodiment, even if not specifically mentioned as being a feature thereof. Thus, the specific details set forth are merely exemplary. The specific details may be varied from and still be contemplated to be within the spirit and scope of embodiments of the present invention.

FIG. 1 is a diagram that illustrates an example system having a storage device, in accordance with some embodiments. A system 100 includes a host device 105 and storage device 110, in the example shown. The host device 105 may include power supply 106 which may be a battery or is associated with an electrical outlet. The host device 105 may also include a host interface 108 to communicate with the storage device 110 via a link 109. It may be noted that the link 109 is used to illustrate one possible connection between the host device 105 and the storage device 110. Other techniques to enable the connection of the host device 105 and the storage device 110 may also be used. For some embodiments, the host device 105 is a mobile device that is configured to perform a certain function. For example, the host device 105 may be a digital camera. The dotted line separating the host device 105 and the storage device 110 is meant to convey that they are separated devices, but the storage device 110 may be coupled with (or plugged into) the host device 105.

FIGS. 2 and 3 are is a block diagrams that illustrate an example system having a storage device, in accordance with some embodiments. A system 200 (inside the dotted lines) may include the storage device 110 and the host device 105. The storage device 110 may include a processor a communication module 220, a memory 225, and flash storage 230. For some embodiments, the storage device 110 may be implemented using a form factor that is commonly used by flash storage device such as, for example, a solid state (SD) card or a universal serial bus (USB, e.g., USB Specification 3.0, Rev. 1.0, Nov. 12, 2008, USB Implementers Forum) thumb drive. One advantage of using the flash memory form factor is that it contains no mechanical parts. As a result, data transfer to and from solid-state storage media may take place at a much higher speed than is possible with electromechanical disk drives. The absence of moving parts may translate into longer operating life, provided the devices are reasonably cared for and are not exposed to electrostatic discharge. However, as compared to electromechanical drives, the flash memory form factor may lag behind the electromechanical drives in terms of storage capacity.

As an example, hard drives commonly hold hundreds of gigabytes (GB) whereas the flash memory USB devices may not be able to store as much. The cost per megabyte (MB) may be higher fir solid-state storage devices than for electromechanical drives. However, the price gap appears to be narrowing, and the market for solid-state storage is may be growing. Many businesses and home users who have multiple computers may favor solid-state storage devices for transferring data among their machines, because it is convenient, compact, and fast.

The illustrated storage device 110 also includes device interface 235 to enable the storage device 110 to interface with the host device 105. For some embodiments, the device interface 235 is configured to conform to existing flash storage (file system) interface. Having the standard form factor and conforming to the existing storage interface may enable the storage device 110 to be used with a host device 105 from many different manufacturers. For some embodiments, the storage device 110 is configured to draw power from the host device 105 when the device interface 235 is coupled with the host interface 108. The power drawn from the host device 105 may be used to power at least the processor 205 and the communication module 220.

The flash storage 230 may be used as a local flash storage. For example, the host device 105 may be a digital camera and digital images captured by the host device 105 may be stored in the flash storage 230. The communication module 220 may be implemented to operate with a Wi-Fi (e.g., Institute of Electrical and Electronics Engineers/IEEE 802.11-2007, Wireless Local Area Network/LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications) network, cellular network (e.g., a “3G” network, a “4G” network) or any type of network that enables the storage device 110 to exchange information with other devices.

With continuing reference to FIGS. 1-3 a block diagram illustrates an example of a storage device exchanging its information, in accordance with some embodiments. The memory 225 of the storage device 110 may be used to store instructions associated with software applications that may be executed by the processor 215. The software applications may include an operating system (OS) for mobile environments (e.g., Android from Google, Inc. of Mountain View, Calif., WebOS from Hewlett-Packard Company of Cupertino, Calif., etc.), a communication application, and any other user applications that may be used to enable the storage device 110 to extend capabilities of the host device 105. For example, applications may be developed, downloaded and run on the storage device 110 to enable transmitting images stored in the flash storage 230 to other devices such as devices 305, 310 and 315.

The storage device 110 may not have a user interface. It may, however, support virtual device interface such as, for example, virtual network computing (VNC) via Wi-Fi, 3G, 4G, etc. VNC is software that makes it possible to view and interact with a computer from any other computer or device connected to the Internet. VNC is cross-platform, so a person using a Windows-based computer can connect to and interact with a UNIX system. For example, when the Android OS is used in the storage device 110, the standard Android graphical user interface (GUI) display may be seen in a VNC client running on some other devices. As another example, the storage device 110 may be configured to execute instructions associated with a web server, and users may interact with the web server in a way that is similar to how the Wi-Fi routers are configured using a Windows-based computer.

With continuing reference to FIGS. 1-4 is a network diagram that illustrates examples of using the storage devices in various applications, in accordance with some embodiments. A network 400 includes multiple connected devices, in the example shown. The network 400 may be the Internet. Connections from the devices to the network 400 may be wired, wireless, or any other types of connection. For some embodiments, the storage device 110 is configured to work with any host devices 105, including existing host devices without having to make any hardware or software modifications to the existing devices. The storage device 110 may remain plugged into the host device 105 for a prolonged period of time, while quietly executing user applications that have been downloaded into the storage device 110.

For example, a digital camera (or host device) 410B equipped with the storage device 110 may send images in real time to a digital photo frame 410D that is also equipped with a storage device such as the storage device 110. As another example, a voice recorder (or host device) 410A equipped with the storage device 110 may automatically send each new snippet of newly recorded voice to a “voice Twitter” social networking site. The voice recorder 410A may also perform automatic transcription and post the text to the Twitter social networking site 405A. As another example, a radio receiver (or host device) 410C that records daily programs may be programmed to deposit its recordings in a home media server 405C or uploading it to a cloud-based service. Other examples include a pocket scanner (or host device) that writes its scanned files to the storage device 110 may be programmed to send the scanned files to an e-reader, which may be similarly equipped with a storage device similar to the storage device 110, and a printer (or host device) that uses the storage device 110 as part of its print queue may easily implement an “email-to-print” feature.

The host devices used in the above examples may be referred to as “dumb” devices which normally would have limited functionalities. However, when pairing with the storage device 110, these “dumb” host devices have significantly more functionalities. For some embodiments, multiple storage devices 110 (together with their corresponding host devices 105) may be configured to work together as a federation to collaboratively perform a single task. This operating system of the storage devices 110 may be configured to recognize the collaboration in order to perform the task.

Having the storage device 110 configured with the features as described in FIG. 2 not only extends the capabilities of the host devices 105, but also enables the manufacturers of the host devices 105 to focus on developing host devices 105 for which they have expertise. For example, camera makers can focus on making cameras with excellent optics, which should be squarely within the camera makers' domain of expertise. These camera makers, on the other hand, may not necessarily be experts in developing social network applications that share images. The makers of the storage device 110 can focus on making low-power, low-cost, high-performance storage devices. Application developers can focus on developing new applications to run on the storage device 110 and extend the functionalities of a wide variety of host devices 105. These three groups of host device manufacturers, storage device manufacturers, and application developers may work independently of one another. For example, an application developed for a particular form of digital picture sharing may run on a storage device that can be plugged into multiple models of digital cameras.

For some embodiments, the user applications developed for the storage device 110 may be stored in cloud-based services associated with a partner. The user applications may then be downloaded to the storage device 110 based on a user of the corresponding host device 105 registering for the services of the cloud. In essence, the cloud-based services may be viewed as an application store for all of the applications developed for the storage device 110. In these scenarios, the local flash storage 230 may be used as a cache. As another example, the user applications may be coupled with network-based image hosting services such as Picasa of Google, Inc. of Mountain View, Calif. As another example, the user applications may be coupled with network-based video hosting services such as YouTube of Google, Inc. As another example, the user applications may be coupled with network-based document hosting services such as Google Does of Google, Inc. There are many other applications that may be used with the storage device 110 using the services available from the cloud-based services and/or from the services connected to the Internet. For some embodiments, computational demands may be offloaded from the storage device 110 (and the processor 215) to server computing systems that are part of the cloud and/or connected to the Internet.

It should be noted that the storage device 110 described herein may be applicable for usage in many different types of consumer electronics. If any examples refer to the use of the storage device 110 in digital cameras or the like, they are only as examples and are not meant to be limiting to those applications. In other words, the storage device 110 may be used in any consumer electronics or host device) that are configured to accept flash memory using the common form factor such as the SD card or a USB thumb drive. Further, the storage device 110 described herein may be configured to operate with user developed applications that may be downloaded and executed by a processor on the storage device 110.

With continuing reference to FIGS. 1-5 is a flow diagram illustrates a process associated with using a storage device, in accordance with some embodiments. The process may start at block 505 where a storage device 110 is configured to operate with a host device 105. This may be based on the storage device 110 conforming to standard form factor such as a USB thumb drive and conforming to existing flash storage interface. The storage device 110 is configured with a processor 215. At block 510, user applications may be loaded into the storage device 110. The user applications may be downloaded from a user application store, from cloud-based application services, etc. The user applications may be stored in the memory 225 of the storage device 110 and instructions from these user applications may be executed by the processor 215. The memory 225 may also be configured to store an OS such as Android from Google, Inc. The OS may be loaded and executed by the processor 215. At block 515, the storage device 110 may be configured to operate using the power from the host device 105. That is, the storage device 110 may not have its own power supply. In alternative embodiments, the storage device 110 may have its own power supply in addition to or instead of drawing the power from the host device 105. At block 520, the storage device 110 may be configured to exchange data with other devices using a communication module of the storage device 110. This may include, for example, transmitting images and/or texts to social networks server computing systems connected to the Internet.

The flow diagram may therefore be associated with a method for enabling a host device to operate with a flash storage device, wherein the flash storage device is configured to operate with its own processor and communication module. The method also includes enabling one or more user applications to be loaded into a memory of the flash storage device, enabling data generated by the host device to be stored in a flash memory storage of the flash storage device, and enabling the one or more user applications to be executed by the processor to process the data generated by the host device, wherein the processor is configured to operate using power supplied by the host device and not by the flash storage device.

Embodiments may also include a storage apparatus having a processor, and a memory module coupled with the processor and configured to store a mobile operating system and one or more user applications. The storage apparatus can also have a device interface configured to couple with an interface of a host device.

The system can also have a first storage device coupled with the host device and having a processor, flash memory storage, and a device interface conforming to a flash memory interface, wherein the first set of data generated by the host device is to be stored in the flash memory storage. The processor may be configured to run one or more user applications to process the first set of data. Additionally, the processor may be configured to operate using power supplied by the host device.

Other embodiments may include a computer readable storage medium having a set of instructions which, if executed by a processor, cause a flash storage device to enable a host device to operate with the flash storage device. The flash storage device may be configured to operate with the processor and a communication module. The set of instructions which, if executed by the processor, can further enable one or more user applications to be loaded into a memory of the flash storage device, enable data generated by the host device to be stored in a flash memory storage of the flash storage device, and enable the one or more user applications to be executed by the processor to process the data generated by the host device.
