Most preferably, the management data includes at least one files directory, wherein at least one files directory includes at least one item selected from the group consisting of: a file name, a file size, a file attribute, and a physical address of a file sector.

Abstract: A memory card includes a memory for storing data and a controller that is operative to control access to storage of at least a portion of storage conditional upon an authorization of a corresponding identity card of a service provider. A storage system includes an identity card of a service provider and a memory card, wherein the identity card corresponds to the memory card, and wherein access to storage of at least a portion of the memory card is controlled conditional upon an authorization from only this corresponding identity card. A method of doing business includes equipping a mobile phone with an identity card that corresponds to a memory card, configuring the memory card to operate conditional on an authorization from this corresponding secured card, and then offering the mobile phone and the memory card for sale at a discount.

Abstract: A data storage device provides information to an application while protecting the information from being copied. Particularly, the data storage device may include a detector to detect an access to an indicator. The indictor may be integrated with the information in such a way that a copy application will access the indicator when copying the information but another application using the information (e.g. a database application) will not access the indicator. The data storage device may further be configured to undertake a defensive response when access to the indicator is detected. Defensive responses may include terminating the access, issuing a report, or sending spurious data to the host. The configuration of the indicator and timing of the response may be chosen to impede separation of the indicator from the data.

Abstract: A controller handles host commands from a host processor and also interfaces the host processor to a serial device. Storage circuitry (e.g., a shift register) of the controller holds a predetermined plurality of data bits. State machine circuitry controls the storage circuitry for serial bit-level communication (e.g., using a PS/2 protocol) between the storage circuitry and the serial device. A processor executes code from a program memory. In particular, the program code causes the processor to detect that a host command has been received by the controller from the host processor and causes an action corresponding to the host command received. Because the processor is not involved with the serial bit-level communication between the storage circuitry and the serial device, the processor executing the software can handle host commands without affecting the serial bit-level communication.
