Claim 0:
1. A method of measuring durability of a nonvolatile memory device that includes a plurality of memory blocks, the method comprising:
periodically receiving a read command for a first memory block among the plurality of memory blocks;
periodically performing a read operation on first memory cells of the first memory block based on the read command, the first memory cells connected to a first wordline, the first wordline being determined in advance of the method of measuring durability;
periodically outputting at least one cell count value associated with the first memory block based on a result of the read operation; and
periodically storing durability information associated with the first memory block in response to a periodic reception of the durability information, the durability information being obtained by accumulating the at least one cell count value.
