  • Publication number: 20190236318
    Abstract: Method and apparatus for managing data in a data storage device configured as a storage compute appliance. In some embodiments, the data storage device has a non-volatile memory (NVM) and a controller circuit. The NVM stores a plurality of data sets encrypted by at least one encryption key. The controller circuit performs a storage compute appliance process by locally decrypting the plurality of data sets in a local memory of the data storage device, generating summary results data from the decrypted data sets, and transferring the summary results data across the host interface to an authorized user without a corresponding transfer of any portion of the decrypted data sets across the host interface.

  • Publication number: 20190236317
    Abstract: Method and apparatus for managing data in a data storage device configured as a storage compute appliance. In some embodiments, the data storage device has a controller circuit and a non-volatile memory (NVM) with an overall data storage capacity. A processor authenticates each of a plurality of authorized users of the NVM via data exchanges between a host device and the processor without reference to an external authentication authority device. Upon authentication, each authorized user is allocated a separate portion of the overall data storage capacity of the NVM using an allocation model. The size of at least one of the separate portions is subsequently adjusted based on an access history of the NVM. The storage device may be a key-value storage device so that a separate set of key values is provided to each authorized user to identify data blocks stored to and retrieved from the NVM.

  • Publication number: 20190075090
    Abstract: Systems and methods for encryption key shredding to protect non-persistent data are described. In one embodiment, the storage system device may include a storage drive and a controller. In some embodiments, the controller may be configured to power on the storage drive, identify an encryption key on the storage drive created upon powering on the storage drive, and encrypt data in a cache of the storage drive using the encryption key. In some embodiments, the controller may be configured to power off the storage drive and delete the encryption key upon powering off the storage drive. In some cases, the storage drive may include at least one of a solid state drive and a hard disk drive. In some embodiments, the storage drive may include a hybrid storage drive that includes both a solid state drive and a hard disk drive.

  • Publication number: 20190042343
    Abstract: Method and apparatus for managing data in a semiconductor memory, such as but not limited to a three dimensional (3D) NAND flash memory array. In some embodiments, the memory has non-volatile memory cells arranged into addressable blocks. Each memory cell is configured to store multiple bits. A program/read control circuit programs data sets to and reads data sets from the memory cells in the addressable blocks to service a sequence of host access commands. The circuit concurrently performs background reads in conjunction with the servicing of the host access commands. The background reads result in the reading of a different data set from each of the addressable blocks over each of a succession of time intervals of selected duration. The background reads condition the memory cells prior to a first read operation associated with the host access commands.
