Products & Technology

Invented the world’s first flash memory

In 1987, the world's first NAND flash memory was developed.
Since then, we have improved our miniaturization technology to achieve more compact integration. Then, in 2007, we pioneered the development of a three-dimensional stacked structure. Chip-stacking technology has enabled us to increase the capacity of flash memory, and has supported the evolution of electronic devices and the development of the information society on a global scale.
