Abstract

An expandable and collapsible peripheral device is disclosed, along with methods of manufacturing same. When in an expanded state, the peripheral device may have a length which conforms to the ExpressCard standard, and when in a collapsed state, the peripheral device may have a form factor approximating that of a CompactFlash card. Peripheral devices of the present invention may operate according to standards other than the ExpressCard standard, and may have sizes in the expanded and collapsed positions unrelated to ExpressCards and/or CompactFlash cards.

Claims (20)

1. A portable memory device movable between first and second physical configurations, the first configuration differing from the second configuration at least with respect to a length of the respective first and second configurations, the portable memory comprising a single electrical interface matable with a host device with the portable memory device in the first and/or second configurations.

2. A portable memory device as recited in claim 1 , wherein the electrical interface is a serial interface.

3. A portable memory device as recited in claim 2 , wherein the serial interface complies with the PCI-Express standard.

4. A portable memory device as recited in claim 2 , wherein the serial interface complies with the USB standard.

5. A portable memory device as recited in claim 1 , further comprising at least one non-volatile memory.

6. A portable memory device having a length smaller than a length defined in the ExpressCard standard and including an interface compatible with the standard PCI-Express interface.

7. A portable memory device as recited in claim 6 , wherein the device is capable of expanding without an adapter to a length defined in the ExpressCard standard.

8. A portable memory device as recited in claim 6 , further comprising at least one non-volatile memory.

9. A portable memory device expandable from a first shape to a second shape that is larger than the first shape, the portable memory comprising a single electrical interface matable with a host device with the portable memory device in the first and/or second shapes, and the portable memory device including a semiconductor memory in the first shape and the second shape.

10. A portable memory device as recited in claim 9 , wherein the electrical interface is a serial interface.

11. A portable memory device as recited in claim 10 , wherein the serial interface complies with the PCI-Express standard.

12. A portable memory device as recited in claim 10 , wherein the serial interface complies with the USB standard.

13. A portable memory device as recited in claim 9 , further comprising at least one non-volatile memory.

14. A portable memory device as recited in claim 9 , wherein the first shape is approximately a size of a CompactFlash card.

15. A portable memory device as recited in claim 9 , wherein the second shape is approximately a size of an ExpressCard.

16. A portable memory device as recited in claim 9 , wherein the first shape has a length of between approximately 40 mm to 45 mm.

17. A portable memory device as recited in claim 9 , wherein the second shape has a length of between approximately 75 mm.

18. A portable memory device as recited in claim 9 , further comprising an actuation system for moving the portable memory device from the first to the second shape.

19. A portable memory device as recited in claim 18 , wherein the actuation system comprises one or more springs for biasing the device into the second position.

20. A portable memory device as recited in claim 18 , wherein the actuation system comprises a mechanical release for releasably holding the device in the first position.
