Abstract: A nonvolatile memory device includes a memory cell array including a main cell area and a retention flag cell area, a retention check unit configured to compare a read result for retention flag cells included in the retention flag cell area to a reference value, and determine a retention state of the retention flag cells according to a comparison result, and a control logic configured to provide a retention check result based on the retention state to the external device in response to a retention check request provided from an external device.

Abstract: A nonvolatile memory system includes a memory area including a nonvolatile memory apparatus divided into a plurality of blocks, and a controller configured to control the memory area. The controller groups the plurality of blocks of the memory area according to wear level and whether each of the plurality of blocks is in use, and manages the blocks of each group in wear level order.
