Portable universal serial bus memory devices and methods for using such devices
View Patent ↗Portable USB memory modules or devices and methods for using such devices are disclosed herein. In one embodiment, a portable memory module can include a housing having a CompactFlash card form factor and one or more flash memory devices carried by the housing. The portable memory module can also include a USB controller carried by the housing and coupled to the one or more flash memory devices. The portable memory module can further include a connector including a first portion coupled to the controller and a second portion configured to mate with a host device. In several embodiments, the connector includes a plurality of pins to transfer signals to and from the memory module. The pins are configured to mate with a fifty pin socket on the host device.
1. A portable memory device, comprising:
a casing having a form factor;
a flash-based hard drive in the casing;
a serial data bus in the casing and coupled to the hard drive, wherein the serial data bus is configured to read data from and write data to the hard drive; and
a connector coupled to the serial data bus and having a plurality of pins configured to transfer signals to and from the memory device, and wherein the pins are configured to interface with a fifty pin socket of a host device,
wherein the fifty pin socket includes pin locations 1 through 50 arranged in a pattern corresponding to a standard socket configuration; and
the connector includes two power lines, seven ground lines, a first data line, a second data line, a reset line, a write protect line, a card detect line, and a status line, and wherein the connector does not include pins corresponding to the remaining pin locations of the fifty pin socket.
2. The memory device of claim 1 wherein the serial data bus is configured to transfer signals using a bulk transfer mode and/or a control transfer mode.
3. The memory device of claim 1 wherein the connector has less than fifty pins.
4. The memory device of claim 1 wherein the casing has a length of 36 mm, a width of 43 mm, and a thickness of 3.3 mm.
5. A method of manufacturing a portable memory module, the method comprising:
providing a housing having a form factor and an external connector including a plurality of pins configured to transfer signals to and from the portable memory module;
installing one or more flash memory devices in the housing; and
installing a serial data bus in the housing and coupling the serial data bus to the one or more flash memory devices and the external connector,
wherein providing the housing having the external connector includes providing the external connector configured to mate with a fifty pin socket on an external host device, and wherein the external connector includes less than twenty pins.
6. The method of claim 5 wherein providing a housing having a external connector includes providing a connector configured to mate with a fifty pin socket on an external host device.
