MEMORY SYSTEM, DATA STORAGE DEVICE, MEMORY CARD, AND SSD INCLUDING WEAR LEVEL CONTROL LOGIC

摘要

PURPOSE: A memory system including abrasion control logic, a data storage device, a memory card, and a solid state drive are provided to improve the performance of the memory system by reducing an ECC error rate and an increase rate of an erasing loop number. CONSTITUTION: A memory system(100) includes a non-volatile memory(110) and an abrasion control logic(126). The non-volatile memory has a user area and a buffer area. The abrasion control logic controls an operation for converting a part of a memory block in the user area into the buffer area based on abrasion information of the non-volatile memory.
