Abstract
A non-volatile memory device which includes a non-volatile memory core including a memory cell array and a controller configured to generate wear-leveling information from internal operation information of the memory cell array after a write operation, independent of a request from an external device. The wear-leveling information is selectively provided to the external device.
Claims12
A non-volatile memory device, comprising:
- a non-volatile memory core comprising a memory cell array;
- and
- a controller configured to generate wear-leveling information from internal operation information of the memory cell array after a write operation, independent of a request from an external device, the wear-leveling information being selectively provided to the external device.
An operating method of a non-volatile memory device, comprising:
- executing a write operation of a selected memory region of the non-volatile memory device in response to a write command;
- and
- after executing the write operation, determining wear-leveling information from internal operation information of the selected memory region,
- wherein the determined wear-leveling information is output in response to an external request.

A memory system, comprising:
- a non-volatile memory device;
- and
- a memory controller configured to control the non-volatile memory device,
- wherein the non-volatile memory device is configured to determine wear-leveling information from internal operation information of a write-requested memory region and to provide the determined wear-leveling information to the memory controller in response to a wear-leveling request of the memory controller.
