Abstract
A storage device performing a purge operation in response to a replay protected memory block (RPMB) purge command comprises at least one nonvolatile memory device; and a storage controller. The storage controller is configured to control data input and data output of the at least one nonvolatile memory device, track a at least one RPMB of the at least one nonvolatile memory device in which RPMB data is stored, and trigger a garbage collection based on a number of the RPMBs reaching a threshold, and the storage controller is further configured to, based on allocating a log block to which write data is to be programmed, give priority to a memory block corresponding to the RPMB among free blocks over a non-RPMB block among the free blocks.
