Operating method of storage controller managing system memory blocks and storage device including the same

Abstract

According to an embodiment of the present technology, a storage device includes a non-volatile memory device including a first memory block area and a second memory block area, and a storage controller configured to control the non-volatile memory device, determine a target erase count based on a generated assignment request among a first assignment request and a second assignment request, and assign a target memory block corresponding to the target erase count, as a memory block corresponding to the generated assignment request, to a shared block pool. The first assignment request corresponds to a memory block of a first type in the first memory block area, the second assignment request corresponds to a memory block of a second type in the first memory block area, and the target memory block is included in the first memory block area.
