NON-VOLATILE MEMORY DEVICE, OPERATING METHOD THEREOF, AND MEMORY SYSTEM HAVING NON-VOLATILE MEMORY DEVICE

摘要

PURPOSE: A nonvolatile memory device, an operating method thereof, and a memory system are provided to increase a lifetime by including a controller for processing abrasion information. CONSTITUTION: A nonvolatile memory core includes a memory cell array(130). A controller(160) generates abrasion information from the inner operation information of the memory cell array. The controller generates abrasion information regardless of the request of the external device. The controller selectively provides the abrasion information to the external device. A register(105) and a counter process the abrasion information and the operation of the core.
