In 1984, we developed a new type of semiconductor memory and named it flash memory (nor), leading the storage industry into the next era. Then, we developed NAND flash memory (NAND). Since then, NAND has been applied to various memory cards and electronic products. NAND market is developing rapidly, and NAND flash memory has become an international standard storage device. As the inventor of flash memory, armor man has opened up a path to a new era of portable video, music and data.
