Kioxia's Research and Technology Development
Chief Technology Officer, Masaki Momodomi
We have realized new products and services that greatly transform society and lifestyles. With our mission to "uplift the world with ‘memory’,” we deliver memory and SSDs that offer high speed, large capacity, and excellent reliability, through active collaborations and personnel exchanges that transcend organizational boundaries.
KIOXIA has developed many “world-first” technologies, such as NAND flash memory and created innovation. As a leading company in “memory,” KIOXIA will continue to work on cutting-edge research and development to create innovation.
This page presents videos of interviews with the "Fellows" who are the power behind the memory research and technology development at KIOXIA. These professionals are masters of devices and processes, memory systems, TCAD simulations and flash memory development. They talk about the pleasure of research and technology development and about KIOXIA's contribution to the world ten years from now.
Technology and Innovation at KIOXIA
As a leading company in flash memory and SSD, KIOXIA conducts research and technology development that supports the information society.
Introducing the relationship between KIOXIA's technology and society, and the "technology" of flash memory, which is the basis of our technology.
Innovations Created by KIOXIA
In 2007, KIOXIA was the first in the world to announce 3D flash memory technology. Here we present the key points of innovation that led to cost reductions and the initiatives for higher capacities, together with an explanation of BiCS FLASH™.
KIOXIA invented the world’s first NAND flash memory in 1987. This is an explanation of the structure of flash memory and the mechanism of data storage.
“Multi-level cell technology” is one of the main technologies realizing larger capacity flash memory. The 1 Gbit MLC NAND flash memory launched by KIOXIA in 2001 was the first application in the world of multi-level cell technology to a NAND flash memory product.
Technology Topics
Introducing latest technologies being researched and developed at KIOXIA Corporation and various use cases of flash memories.

Selector devices are key components for next-generation high-density memory cell arrays. In this work, the reliability of selector devices has been studied in collaboration with imec, the world-leading R&D center in electronics technologies. The mechanism of the cycling-dependent threshold voltage instability has been clarified by combining electrical characterization and modeling techniques. These results were presented at the international conference IEDM2022.

As the demand for larger memory capacities has rapidly increased, a high etch rate for a high aspect ratio structure is significantly required for high productivity. We have modeled ion-induce surface reactions and developed a simulation technique for predicting the optimal ion species for the etching process of the memory hole because ion species play a dominant role in high aspect ratio etching.

We developed a Memory-Centric AI-based image classification system that utilizes high-capacity storage to enable knowledge expansion while avoiding catastrophic forgetting. It improves explainability of AI by retaining the reference images used for classification.
KIOXIA's R&D Backgrounds
KIOXIA covers from R&D to mass production of flash memory and SSD products. Introducing the mechanisms of technological innovation, that is, how R&D is conducted in the process of bringing our products to market.
Introducing KIOXIA’s achievements in supporting the evolution of electric devices, such as the invention of NAND flash memory in 1987, and advancement of the information society on a global scale, seen through the lens of the history of memory and SSD development.
KIOXIA has been highly commended for the presentation of its R&D through a variety of channels, including major academic societies and research papers.
R&D Organization/Academic Collaboration
