Abstract

This disclosure is directed to a compact storage device, such as a flash memory device. The connector of the memory device contains the controller that controls data transfer and storage within a flash memory module (FMM) of the memory device. Preferably, the controller resides completely within the connector to enable the smallest form factor of the flash memory device and the most space for one or more flash memory modules. In this manner, the memory device may store a large quantity of data while being of a small size. Additionally, the connector may also be used with other data transfer or storage devices while the FMM may separately store data within other storage or computing devices.

Claims

1. A device for storing data, the device comprising:

a device housing;

a memory module within the device housing that stores data; and

a connector that extends from the device housing comprising;

a plurality of electrical contacts that facilitate a connection to a host port; and

a controller circuit that manages data transfer and data storage to the memory module, wherein the controller resides outside of the device housing.

2. The device of claim 1, wherein the controller circuit resides completely within the connector.

3. The device of claim 2, wherein the controller circuit is embedded within a connector housing.

4. The device of claim 1, wherein the host port is electrically coupled to a computing device, and wherein the controller circuit supports inserting the connector into and removing the connector from the host port while a computing device connected to the host port is operating.

5. The device of claim 1, wherein the connector is a standard universal serial bus (USB) connector.

6. The device of claim 1, wherein the connector and the device housing each house a printed circuit board.

7. The device of claim 1, wherein one printed circuit board resides within both the connector and the device housing.

8. The device of claim 1, wherein the memory module is removable from the device housing.

9. The device of claim 1, wherein the memory module is a nonvolatile memory module.

10. The device of claim 1, wherein two or more memory modules reside within the device housing.

11. A removable connector for a first device, the device comprising:

a plurality of electrical contacts that facilitate a connection of the first device to a port of a second device; and

a controller circuit that manages data transfer between the second device and the first device when the first device and the second device are connected via the removable connector, wherein the removable connector is removable from the first device.

12. The removable connector of claim 11, wherein the controller circuit resides completely within a connector housing.

13. The removable connector of claim 12, wherein the controller circuit is embedded within the connector housing.

14. The removable connector of claim 11, wherein the controller circuit includes protection circuitry to protect the removable connector from a power surge upon insertion of the removable connector into the second device while the second device is operating.

15. The removable connector of claim 11, wherein the connector is a standard universal serial bus (USB) connector.

16. The removable connector of claim 11, further comprising a removable memory module, wherein the controller circuit is electrically coupled to the memory module with a module connector.

17. A memory module for storing data, the memory module comprising:

a circuit board;

a plurality of electrical contacts that facilitate a connection to a host device; and

a memory circuit coupled to the circuit board, wherein the memory circuit includes protection circuitry to protect the memory circuit from a power surge upon insertion of the memory module into the host device while the host device is operating.

18. The memory module of claim 17, wherein the memory circuit is a flash memory circuit of a thin small outlined package (TSOP).

19. The memory module of claim 18, further comprising a keyed slot on an edge of the circuit board, wherein the electrical contacts are located along the edge.

20. The memory module of claim 17, wherein the memory circuit stores data within a universal serial bus (USB) memory device.
