Abstract
A nonvolatile memory device includes a plurality of memory blocks. The nonvolatile memory device includes a controller configured to perform an erase operation by repeating an erase loop, and generates and stores a test result based on a pass erase loop count of the erase operation in response to a result processing command. The erase loop includes applying an erase voltage to a target memory block among the memory blocks in response to an erase command.
