Samsung, SK Hynix reportedly upgrading China NAND fabs to fend off YMTC amid softening US stance

Samsung Electronics and SK Hynix are upgrading their NAND flash factories in China to make chips with more than 200 layers, Reuters reported on October 21, citing four people familiar with the plans. The move would let the South Korean memory makers win back ground lost to Yangtze Memory Technologies Co (YMTC), even though US curbs on upgrading their China operations remain formally in place.
