Well-known Chinese news site NetEase (NASDAQ: NTES) recently reported that Micron, Huawei’s sole primary memory and flash memory supplier for 20 years, announced compliance with the U.S. ban on Huawei. This is another major blow to Huawei’s supply chain after TSMC’s similar announcement. Micron is the world’s largest semiconductor memory vendor. Micron, Samsung and Hynix together own 95 percent of the world’s DRAM market. Micron is also one of the six vendors that together hold 99 percent of the world’s NAND flash memory market. The only hope Huawei has now is to obtain domestic support from Yangtze Memory Technologies for NAND, ChangXin Memory Technologies (CXMT) for DRAM, and Jinhua Integrated Circuit (JHICC) for DRAM. However, the U.S. already banned JHICC in 2018, due to a lawsuit that Micron filed for unauthorized use of intellectual properties. Yangtze Memory’s manufacturing process depends heavily on high-end equipment like the mask aligners from the Netherland’s SAML, which also uses U.S technology. If the U.S. blacklists the other two Chinese domestic suppliers, Huawei will face a death sentence on the memory side too, in addition to the central processing chips.
