    摘要： In some embodiments, after a hold off time following issuance of a memory command has elapsed, a status read operation is performed to determine a status of the memory command. In some embodiments, if the memory command has not yet completed, a polling interval is used to perform a status read operation to determine the status of the memory command after the polling interval has expired, and repeating the process until the memory command has been completed. Other embodiments are described and claimed.

    摘要： One aspect of the invention provides a novel scheme to preserve the failure state of a memory location. According to one embodiment, the data is read from a memory location in a read-destructive memory device. If the data is found to be valid (uncorrupted) it is written back to the memory location from where it was read in order to preserve it. If the data is found to be invalid (corrupted) then a failure codeword is written in the memory location to indicate a failure of the memory location. The failure codeword may be preselected or dynamically calculated so that it has a mathematical distance greater than all correctable data patterns.

    摘要： A video source device includes a cipher unit. The cipher unit includes a block cipher and a stream cipher. The video source device uses the block cipher to generate at least one cipher key for use by the stream cipher to generate cipher bits for ciphering video to be transmitted to a video recording device. The video source device further provides n bits of copy control information to the video recording device. The video source device incorporates the n-bit copy control information as part of an initialization value, and initializes a register of a round function of the block cipher with the initialization value. The video recording device also includes a cipher unit of like kind, and operates the block and stream ciphers in like manner to decipher the ciphered video received from the video source device. Upon receiving the n-bit copy control information, the video recording device also forms an initialization value and initializes a corresponding register of the corresponding round function of its block cipher. Accordingly, protection is provided to the copy control information.

    摘要： A nonvolatile storage or memory device is accessed over a memory bus. The memory bus has an electrical interface typically used for volatile memory devices. A controller coupled to the bus sends synchronous data access commands to the nonvolatile memory device, and reads the response from the device bus based on an expected timing of a reply from the nonvolatile memory device. The controller determines the expected timing based on when the command was sent, and characteristics of the nonvolatile memory device. The controller may not need all the electrical signal lines available on the memory bus, and could issue data access commands to different groups of nonvolatile memory devices over different groups of electrical signal lines. The memory bus may be available and configured for either use with a memory controller and volatile memory devices, or a storage controller and nonvolatile memory devices.

    摘要： Techniques for determining an identifier for a volume of memory in a memory device of a computer system. In an embodiment, the memory device detects an indication of an initialization event of the computer system and receives command information after the detecting of the indication. In certain embodiments, the memory device stores an identifier value for association with the volume of memory, wherein the storing is based on whether the received command information specifies that the volume of memory is to be assigned an identifier.
