Abstract
A NAND flash memory device having memory cells for storing data includes a fuse circuit configured to store option information for operation of the NAND flash memory device as logic codes. A register circuit includes registers for temporarily storing the logic codes stored in the fuse circuit. A test circuit is configured to change the logic code stored in the register circuit and store the changed logic code irrespective of the logic code of the fuse circuit for test operation of the NAND flash memory device. A processor is configured to control operation of the NAND flash memory device.
