Susumu Yoshikawa
Director
Institute of Memory Technology Research and Development

In order to meet the demands of a "new era of memory" where there is an explosive increase in the volume, types, and application of data, our Institute of Memory Technology Research and Development has been researching next-generation flash memory, new types of high value-added memory devices, process technologies, and new types of storage computing system technologies, and state-of-the art digital transformation* technology such as machine learning. As a result, we have been able to develop innovative products that enrich people’s lives and provide society with new sources of value.

 

The Institute of Memory Technology Research and Development is the most advanced technical research institute of KIOXIA Corporation and we operate four technology development centers for devices, processes, system, and digital transformation in the Yokkaichi area and the Tokyo-Yokohama area in order to conduct innovative research and apply the results across various fields and industries. In addition, our institute is also utilizing open innovation to promote active collaboration with universities and research institutes around the world so that we can equip engineers with new skills and expertise that can help them be successful in their international endeavors.

 

We are constantly reviewing our work, carrying out research free of conventional constraints and without fear of failure, and eagerly and boldly pursuing our lofty goals so that we can "uplift the world with 'memory.'"

we operate four technology development centers for devices, processes, system, and digital transformation.

Device Technology Research & Development Center

In order to realize the most advanced memory products, it is necessary to develop new memory cell materials, structures, and devices such as transistors to operate peripheral circuits, as well as process integration technology, circuit design technology and TCAD technology.

 

The Device Technology Research & Development Center develops these technologies and utilizes them to develop next-generation file memory with even higher density or new nonvolatile memories such as storage-class memory. It also develops simulation programs and applies them to actual devices. It creates the concepts of brand-new memories and develops memory circuit design technology based on the concepts and designs prototype products. It also performs fundamental research of materials and structures for new memories that have yet to see the light of day, based on new concepts and physical phenomena, with a 10-year time horizon.
