摘要： A memory device with circuitry for improving accuracy of a time estimate and a method for use therewith are disclosed. In one embodiment, a memory device receives a time stamp and measures active time with respect to the received time stamp. The memory device determines accuracy of previously-measured active time and generates a time estimate using the measured active time, the accuracy of previously-measured active time, and the received time stamp. In another embodiment, measured active time is adjusted, with or without generating a time estimate. Other embodiments are disclosed, and each of the embodiments can be used alone or together in combination.

摘要： A storage device and method for dynamic content tracing are provided. In one embodiment, a storage device stores content having a plurality of sequences of data, each sequence of data having original data and at least one variation of the original data. The storage device receives an identifier of a host device and, for each sequence of data, selects either the original data or one of the at least one variation of the original data based on the identifier of the host device. The storage device then assembles a version of the content from the selections and provides the assembled version of the content to the host device. The assembled version of the content is unique to the host device and therefore can be used to trace the assembled version of the content back to the host device.

摘要： A memory device with circuitry for improving accuracy of a time estimate used in digital rights management (DRM) license validation and a method for use therewith are disclosed. In one embodiment, a memory device receives a request to validate a DRM license stored on the memory device, wherein the DRM license is associated with a time stamp update policy (TUP) that specifies when a new time stamp is needed. Before attempting to validate the DRM license, the memory device determines if a new time stamp is needed based on the TUP associated with the DRM license. If a new time stamp is needed, the memory device receives the new time stamp and then attempts to validate the DRM license using a time estimate based on the new time stamp. Other embodiments are disclosed, and each of the embodiments can be used alone or together in combination.

摘要： A method and system for content replication control are provided. In one embodiment, a content replication system (100) receives a request to replicate content in a plurality of memory devices (130), wherein each memory device is associated with a respective unique identifier. For each of the plurality of memory devices, the content replication system sends a request to a transport encryption key server (110) for a transport encryption key, the request including the unique identifier of the memory device. If the unique identifier of the memory device is authorized to receive the transport encryption key, the content replication system receives the transport encryption key and sends the transport encryption key to the memory device. The content replication system then receives encrypted content from a content server (120), wherein the encrypted content is encrypted with the transport encryption key. The content replication system then sends the encrypted content to the plurality of memory devices.
