Abstract: A system and method for automatic deletion in a persistent storage device. In some embodiments, the method includes: receiving, by a persistent storage device, a first read command, for a first logical block of data; determining that a total number of read operations, for the first logical block of data, equals or exceeds a first threshold value; and in response to determining that the total number of read operations, for the first logical block of data, equals or exceeds the first threshold value, arranging for deletion of the first logical block of data from the persistent storage device.

Abstract: A method may include receiving, at a memory system having a block modification characteristic, a write request for a data structure arranged in the memory, storing, based on the write request, data in the data structure, receiving, at the memory system, a read request for the data structure, reading, based on the read request, the data from the data structure, and indicating, based on the reading, the data for modification. The method may further include receiving, at the memory system, a second write request for the data structure, wherein the first write request and the second write request have an order, storing, based on the second write request, second data in the data structure, and determining, based on the read request, based on the order, the first data, wherein the reading may be further based on the determining.

Abstract: A storage device is disclosed. The storage device may include a host interface to receive a write request from a host, the write request may include a data and a logical address of the data. The storage device may further include a first storage for the data. The storage device may further include a retention period determiner to determine a retention period for the data. The storage device may further include a translation layer to select a physical address in the first storage to store the data based at least in part on the retention period. The storage device may further include a second storage for a logical-to-physical mapping table to map the logical address to the physical address and the retention period. Finally, the storage device may include a controller to program the data into the physical address in the first storage.
