1. A unitary portable data storage device comprising:
- a universal serial bus (USB) plug integrated into the unitary portable data storage device without an intervening cable capable of coupling the unitary portable data storage device directly to a USB socket of a computer;
a single interface coupled to the USB plug, the interface allowing the unitary portable data storage device to communicate via the USB protocol;
a non-volatile solid-state memory, the memory having sufficient capacity to enable the unitary portable data storage device to serve as an alternative to a magnetic disk or CD; and
a memory control device coupled between the interface and the memory to control the flow of data between the memory and the USB plug in a manner to enable the unitary portable data storage device to serve as an alternative to a magnetic disk or CD and to implement access restriction wherein access to at least a portion of the data in the memory is restricted absent password authentication.

10. An integrated portable data storage device comprising:
-
a universal serial bus (USB) plug integral to the integrated portable data storage device, the integrated portable data storage device capable of being directly connected to a USB socket of a computer via the USB plug such that there is an immediate connection between the integrated portable data storage device and the computer without cable interconnection; a single interface coupled to the USB plug, the interface allowing the integrated portable data storage device to communicate via the USB protocol; a non-volatile solid-state memory, the memory having sufficient capacity to enable the integrated portable data storage device to serve as an alternative to a magnetic disk or CD; and a memory control device coupled to the memory to control the flow of data between the memory and the USB plug in a manner to enable the integrated portable data storage device to serve as an alternative to a magnetic disk or CD and to implement access restriction wherein access to at least a portion of the data in the memory is restricted absent password authentication; and wherein the USB plug, the memory and the memory control device are part of an integrated housing with a portion of the USB plug protruding from a side wall of the integrated housing to facilitate direct coupling to the USB socket. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
