The
authorization allows them to continue their Chinese chipmaking
operations without the headache of applying for U.S. licenses to
get new equipment, after new rules issued last October curbed
Chinese chipmakers' access to the coveted tools.
The October 2022 rules restricted shipments of advanced chips
and chipmaking equipment to China as part of a U.S. bid to slow
China's technological and military advances.
The U.S. then scrambled to give foreign chipmakers special
authorizations to avoid the unintended consequences of those
rules hitting their production. Friday's release formalizes and
extends those authorizations.
Taiwan Semiconductor Manufacturing Co (TSMC) said in a statement
on Friday that it has been authorized to continue operate in
Nanjing and is in the process of applying for a permanent
authorization for its operations in China, which it expects to
receive.
Samsung Electronics makes about 40% of its NAND flash chips at
its plant in Xian, China, while SK Hynix makes about 40% of its
DRAM chips in Wuxi and 20% of its NAND flash chips in Dalian.
The companies together controlled nearly 70% of the global DRAM
market and 50% of the NAND flash market as of the end of June,
data from TrendForce showed.
