    摘要: A portable data storage device is disclosed which includes an Interface for enabling the portable data storage device to be used for data transfer with a host Computer, and an Interface controller for controlling the interface. There is also a master control unit for controlling the writing of data to and reading data from a non-volatile memory. The non-volatile memory includes at least one single layer cell flash memory and at least one multiple layer cell flash memory. Upon receiving a write instruction, the master control unit determines which of the memories data contained in the instruction should be written to, and writes the data as appropriate similarly, upon receiving a read instruction, the master control unit reads the data from the appropriate one of the memories and transmits the data out of the device.

    摘要: A method for authentication of an external storage device (16) operatively connected to a port of a host computer (10) where the host computer (10) conducts a handshake with the external storage device (16) seeking an authentication key from the external storage device. The host computer (10) electrically disconnects the external storage device (16) from the host computer (10) if the authentication key is incorrect or not provided within a predetermined period. The host computer (10) allows access to the host computer (10) by the external storage device (16) if the authentication key is correct and provided within the predetermined period. Corresponding apparatus and systems are also disclosed.

    摘要: A tri-level authentication process comprises performing a biometrics-based authentication of a user of a portable device, performing an authentication handshake between the portable device and a content server, wherein the portable device includes a USB plug that plugs directly into a USB port of a host computer and the host computer is communicatively coupled to the content server, and performing a user authentication using a first key sent from the portable device to the content server, wherein access to restricted content on the content server by the user is enabled if the biometrics-based authentication, the authentication handshake, and the user authentication using a first key are all successful. The process may also include encrypting restricted content received from the content server using a private key before storing the restricted content in a non-volatile memory of the portable device.

    摘要: A portable data storage device includes a USB interface (3), a USB controller (2), a master control unit (7), and two or more NAND flash memory devices (9, 19). The master control unit (7) can send data to the NAND flash memory devices (9, 19) simultaneously through parallel respective 8-bit buses. The master control unit (7) controls the operation of the memory devices (9, 19) by sending them identical control data through respective control signal lines (6, 16). When data is to be stored it is divided into portions which are sent to the respective memory devices (9, 19), and both memory devices are instructed to store data simultaneously. When data is to be retrieved both are instructed to write data back simultaneously to the MCU.
