MEMORY SYSTEM AND OPERATING METHOD THEREOF

摘要

A memory system includes a non-volatile memory device including a plurality of pages and a controller connected electrically with the non-volatile memory device and configured to control the non-volatile memory device. The non-volatile memory device is configured to be capable of storing data from a set number of write operations before data erasing with respect to each page; and wherein the controller is configured to divide each page of the non-volatile memory device into first and second areas, to perform a write operation of the first area by the NOP, and to write an invalidation mark in the second area.
