CTO Message

We drive forward with leading-edge R&D to create a new era of memory.

We are aiming to “uplift the world with memory” by conducting cutting-edge research and technology development, leveraging the expertise that enabled us to release the world’s first NAND flash memory and 3D flash memory.

In order to facilitate the realization of environmentally-friendly computing while meeting the needs created by technologies such as smartphones, IoT devices, 5G networks, artificial intelligence (AI), and autonomous driving, our company has been prioritizing the development of new types of memory devices and storage systems. To achieve this, we have been working across organizational boundaries in the development and application of technologies for devices, circuits, processes, and systems, including AI based production technologies, while also seeking to solve challenges through creative and flexible solutions that are free from conventional constraints.

In addition to spurring in-house development initiatives, we are actively promoting people to people exchanges for open innovation through collaboration with our customers and partners, as joint efforts between industry and academia. These efforts contribute to fostering young scientists and engineers both inside and outside the company and supporting their R&D activities.

Our company has been utilizing developments in memory-centric semiconductor technologies to create new products and services that have played a major role in transforming society and life. We will continue our pioneering endeavors in the industry through the development of NAND flash memory and high-capacity, high-performance 3D flash memory (BiCS FLASH™) in order to provide the world with memory devices and SSDs distinguished by their speed, capacity, and reliability.
