YMTC's 128-Layer 1.33Tb QLC 3D NAND memory is close to the state of the art. Samples are widely available and volume production is set for this year. It is currently shipping a 64 layer version by the millions. It just broke ground on a new building that will "triple its output capacity to 300,000 wafer equivalents a month." The Wuhan site has an investment budget of US$24 billion, some provided by the province of Hubei. It maintained production despite being in the early world center of the pandemic.
While most of its 2000 engineers are trained in China, it's led by Dr.Simon Yang. Western-educated, he was previously at Intel and CTO of leading foundry Chartered Semiconductor (Now Global Foundries.) A huge percentage of leading chip engineers are Chinese and many are being offered lucrative deals to work in China.
SMIC, China's leading foundry, skipped two generations and now is producing 12-14nm chips. It's N+1 process, expected by the end of the year, is not the same as the 7nm at TSMC but it incorporates many of the Improvements of that generation. The US for now is forbidding ASML in the Netherlands from delivering the EUV machine needed to do better than that. It will take time for China to develop EUV technology of its own, a major obstacle.
There's a myth that China cannot build advanced chips. There's nothing about being born in Taiwan or Oregon that makes you more able to manufacture chips.Add a comment
