Korea-based SK Hynix Inc., which bought Intel's NAND business in 2020, also posted fourth-quarter earnings for fiscal year 2022 Tuesday. It reported a quarterly operating loss ratio of 22%, marking its first quarterly loss in 10 years. SK Hynix is also suffering due to the drop in prices and will continue with the 50% reduction in investment and a reduction in overall production that it announced in October 2022. The company will continue to mass produce its DDR5 DRAM and 238-layer 4D NAND, it said.
