Abstract: A method for managing a replay protection memory block (RPMB) of a storage device includes allocating an RPMB master region managed separately from an RPMB region in which an RPMB key is stored in the RPMB of the storage device, programming a master key into the RPMB master region responsive to a request from a host, receiving a reset request for the RPMB region using the master key from the host, resetting the RPMB key in response to the reset request for the RPMB region, and receiving a reset lock request for the RPMB region from the host.

Abstract: A user device includes a storage device including a flash memory; and a host connected to the storage device via an interface and adapted to transmit data to the storage device. The host provides the storage device with erase count information of the flash memory using a host flash translation layer (FTL), provides the storage device with reprogram information when the flash memory uses a reprogram method, or provides the storage device with page offset information of an open block of the flash memory.
