摘要:
Disclosed is a memory system which includes a nonvolatile memory having a user area and a buffer area; and wear level control logic managing a mode change operation in which memory blocks of the user area are partially changed into the buffer area, based on wear level information of the nonvolatile memory.
摘要:
A method is provided for performing wear-leveling in a memory system comprising a nonvolatile memory device and a memory controller configured to control the nonvolatile memory device. The method comprises setting a wear-level grade for each of a plurality of memory blocks based on a plurality of wear parameters, and determining an order in which to perform program and/or erase (P/E) operations on the memory blocks based on their respective wear-level grades.
