ABSTRACT:
Disclosed herein is a NAND flash memory device capable of changing a block size. In NAND flash memory devices capable of changing a block size, each memory block is divided into two page groups. Each memory block includes two block switches to select each page group in response to an external address signal. During an erasing operation, the block size is easily variable by applying an erasure voltage to one or two page groups.
