NON-VOLATILE MEMORY SYSTEM AND METHOD OF MANAGING A MAPPING TABLE FOR THE SAME

摘要

A non-volatile memory system includes a NAND flash memory device which has a NAND flash memory and a NAND controller controlling the NAND flash memory; and a host device which has a file system and a host controller which receives commands from the file system and provides the commands for the NAND flash memory device. A NAND mapping table is included in the NAND flash memory device, and a host mapping table is included in the host device. The NAND mapping table and the host mapping table are synchronized with each other to perform an address mapping operation first in the host device.
