摘要： A method and memory device for implementing long operations and supporting multiple streams are provided. In one embodiment, a memory device receives data and a command from a host to perform an operation on the data, wherein a time required for the memory device to complete the operation exceeds a maximum response time for the memory device to respond to the command. The memory device begins performing the operation on the data and, before exceeding the maximum response time and before completing the operation, sends the context of the operation to the host. At a later time, the memory device receives from the host: (i) a command to resume performing the operation and (ii) the context. The memory device then resumes performing the operation on the data based on the context received from the host.

摘要： A memory device for using time from a trusted host device and a method for use therewith are disclosed. In one embodiment, an application on a memory device receives a request to perform a time-based operation from an entity authenticated by the memory device, wherein the entity is running on a host device. The application selects time from the host device instead of time from a time module on the memory device to perform the time-based operation and uses the time from the host device to perform the time-based operation. Other embodiments are disclosed, and each of the embodiments can be used alone or together in combination.

摘要： An object known as an identity object comprises a public key and a private key pair and at least one certificate issued by a certificate authority that certifies that the public key of the pair is genuine. This object may be used as proof of identification by using the private key to sign data provided to it or signals derived from the data. An identity object may be stored in a non-volatile memory as proof of identity. The memory is controlled by a controller. Preferably, a housing encloses the memory and the controller. The memory system is removably connected to a host device. After the host device has been successfully authenticated, the private key of the object is used to encrypt data from the host device or signals derived from said data, and the at least one certificate and the encrypted data or signals are sent to the host device. After an entity has been authenticated by a control data structure of the memory system, the public key of the identity object and the at least one certificate to certify the public key are provided to the entity. If encrypted data encrypted by means of the public key of the identity object is received from the entity, the memory system will then be able to decrypt the encrypted data using the private key in the identity object.

摘要： Enhanced configuration of security and access control for data in a storage device is disclosed. A request is received to access an addressable memory location in a storage media within the storage device. A set of addressable memory locations with contiguous addresses identified by an address range is associated with first and second characteristics. The first characteristic is applied if the addressable memory location is within the set of addressable memory locations, and an entity is currently authenticated to and authorized to access the set of addressable memory locations. The second characteristic is applied if the addressable memory location is within the set of addressable memory locations, and no entity is currently authenticated to and authorized to access the set of addressable memory locations. The set of addressable memory locations can also be a logical partition, where the first and second characteristics are stored in a logical partition table.

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 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 memory storing public and confidential information is removably connected to a host device. General information on data stored in memory devices is accessible to the host device without authentication. Only a portion of confidential information stored in the memory device is accessible through the host device to an authenticated entity, where the entity has access rights to such portion. The entity is not able to access other portions of confidential information to which it has no rights. The public and confidential information is stored in a non-volatile storage medium, and a controller controls the supply of information. Preferably, the non-volatile storage medium and the controller are enclosed in a housing.

摘要： A memory system comprises an encryption engine implemented in the hardware of a controller. In starting up the memory system, a boot strapping mechanism is implemented wherein a first portion of firmware when executed pulls in another portion of firmware to be executed. The hardware of the encryption engine is used to verify the integrity of at least the first portion of the firmware. Therefore, only the firmware that is intended to run the system will be executed.
