  • Patent number: 12287968
    Abstract: A memory system includes at least one memory device that includes memory areas. The memory system includes a device allocation manager and security erase circuitry. The device allocation manager determines which of the memory areas is allocated or released based on a request input from at least one host. The security erase circuitry stores a security erase task for a first memory area, which is associated with a release determined by the device allocation manager, in an erase job queue, and removes the security erase task from the erase job queue when the first memory area is reallocated to a first host to which the first memory area was allocated before the release.
