SK hynix has just announced that it's developed the industry's highest 238-layer NAND flash, with its latest 238-layer 512Gb triple-level cell (TLC) 4D NAND flash going out to customers and starting mass production in 1H 2023.
In a statement during Flash Memory Summit 2022 (FMS 2022), SK hynix said: "The latest achievement follows development of the 176-layer NAND product in December 2020. It is notable that the latest 238-layer product is most layered and smallest in area at the same time".
Jungdal Choi, Head of NAND Development at SK hynix said during his FMS 2022 keynote: "SK hynix secured global top-tier competitiveness in perspective of cost, performance and quality by introducing the 238-layer product based on its 4D NAND technologies. We will continue innovations to find breakthroughs in technological challenges."
We only just heard about Micron's new 232-layer B58R TLC NAND flash, used in a new AMD + Phison Gen5 SSD tease, powered by an X670 motherboard and Zen 4-based Ryzen 7000 series CPU.
