Kioxia’s Research and Technology Development
Chief Technology Officer, Hideshi Miyajima
Kioxia conceived and developed the world’s first NAND flash memory and 3D flash memory BiCS FLASH™, and we remain committed to promoting research and development in the future in order to realize our mission of “Uplifting the world with memory.”
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.
The Shining Sun and the Flash Memory for Storage
~ Principle of 3D Flash Memory Operation ~
The principle of 3D flash memory operation is explained with CG animation by contrasting it to the way the sun shines.
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.

Rapid advances in Artificial Intelligence and Machine Learning are increasing the demand for non-volatile emerging memories with high speed operation. We have demonstrated, for the first time, memory operation of Channel-All-Around FeFET, and realized high ΔIon>2μA and stable endurance (>106cycle) in the smallest footprint ever (707nm2).

A state-of-the-art fluorine-free word line (WL) molybdenum (Mo) process has been established for future 3D flash memory. Application of Mo to WLs can accelerate scaling of cells in both the vertical and horizontal directions with lower RC delay and lower leakage failure rates compared to traditional tungsten. These results were presented at VLSI 2024.

September 10, 2024 KIOXIA Multi-level technology Frontier Technology R&D Institute (System Technology)
As the number of multi-level increases from MLC, TLC and QLC, while the memory density can be increased, the number of reads increases and random access deteriorates. We reported on a new multi-level coding method that reduces the number of reads and enables high-speed random access while maintaining a high memory density by sharing data among multiple memory cells.
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
KIOXIA has established industry-leading R&D frameworks with “memory” technology. We use our various locations to conduct technological innovation while promoting open innovation.
To further accelerate the development speed and address the needs of increasingly diverse research themes, KIOXIA promotes R&D projects in collaboration with universities, technical communities, and research institutes both in Japan and abroad.
