China’s YMTC Introduces Chip With 232 Layers of Memory Cells to Catch Up With Micron, SK Hynix

Chinese chipmaker Yangtze Memory Technologies Ltd (YMTC) on Wednesday announced new memory chip technology that would help it catch up with rivals Micron and SK Hynix, just as Washington considers steeper curbs on Chinese semiconductor companies.

The company unveiled its fourth-generation 3D NAND chip, the X3-9070, and its first to feature 232 layers of memory cells, government-backed media outlet Global Times reported on Wednesday.

That places it close to rival Micron, which last month said it aimed to start mass production of its 232 layer chip by the end of the year.

South Korea's SK Hynix has also developed its first 238-layer memory chip, boasting a new industry benchmark.

A YMTC spokesperson declined to comment on the Global Times report.

Industry experts say that while YMTC will unlikely launch mass production of the chip any time soon, it nevertheless marks a breakthrough for the company.

The company's market share remains in the single digits, but it is aggressively expanding production capacity and R&D with the help of state subsidies.

Toby Zhu, who tracks China's chip sector at research firm Canalys, says that while the YMTC's revenue has improved over the years, gaps remain between it and market leaders.

Once a little-known player backed by the ailing Chinese state-conglomerate Tsinghua Unigroup, YMTC has attracted attention in the chip industry for its fast advancements in R&D.

Bloomberg reported in March that phone maker Apple was considering using YMTC as a memory chip supplier, which would mark a major boon for the upstart company.

Reuters reported earlier this week that Washington, citing a growing threat from China, is considering placing restrictions on companies that supply to YMTC, forbidding equipment makers from selling parts to the company that enable it to manufacture chips at 128 layers and above.

The restrictions, if enacted, could rattle YMTC's ambitions to grow its business, not unlike how sanctions in 2020 rattled Chinese phone maker Huawei Technologies Ltd.
