Abstract: A data storage device is provided. The data storage device includes a storage medium having a first subset configured to store user data and a second subset configured to store snapshot data. The data storage device further includes a controller configured to (i) receive, from a host operably coupled to the data storage device, a command to configure the second subset, to (ii) verify an authenticity of the command, and to (iii) execute the command in response to the verification of the authenticity of the command.

Abstract: The present disclosure includes apparatuses and methods for directed sanitization of memory. One example method comprises, responsive to receiving a sanitization command, performing a deterministic garbage collection operation on a memory, wherein performing the deterministic garbage collection operation results in physical erasure of all invalid data stored on the memory without losing valid data stored on the memory.

Abstract: An apparatus for performing secure operations with a dedicated secure processor is described in one embodiment. The apparatus includes security firmware defining secure operations, a processor configured to execute the security firmware and perform a set of operations limited to the secure operations, and a plurality of secure hardware registers, accessible by the processor and configured to receive instructions to perform the secure operations. An apparatus for performing secure operations with a plurality of security assist hardware circuits is described in another embodiment. The apparatus comprises one or more secure hardware registers configured to receive a command to perform secure operations and one or more security assist hardware circuits configured to perform discrete secure operations using one or more secret data objects.

Abstract: An example method of encoding data attributes by data stream identifiers includes: receiving, by a controller managing a memory device, a write command, wherein the write command specifies a first data item and an identifier of a data stream, wherein the data stream comprises the first data item and a second data item; determining, by parsing the identifier of the data stream, a data attribute encoded by the identifier of the data stream, wherein the data attribute is shared by the first data item and the second data item; determining, using the data attribute, a storage operation parameter; and transmitting, to the memory device, an instruction specifying the first data item and the storage operation parameter.

Abstract: A processing device receives a first instruction specifying that first data is to remain on a first memory device of a plurality of memory devices, the first memory device comprising a first media having a first media type. The processing device further receives a second instruction specifying, based on one or more criteria, that second data is to be moved from the first media having the first media type to a second memory device of the plurality of memory devices, the second memory device comprising a second media having a second media type that is different than the first media type. The processing device further controls the first and second data in the plurality of memory devices based on the first instruction and the second instruction.
