Samsung and SK Hynix upgrading China plants to make more advanced chips: Reuters

The upgrades would lift output to more than 200 layers as the companies seek to match South Korean production and counter YMTC’s gains, Reuters said.

  • On Tuesday, October 21, Samsung Electronics and SK Hynix confirmed they are upgrading Chinese NAND memory factories to produce more advanced chips, aiming to meet rising global artificial intelligence demand.
  • These upgrades proceed despite strict U.S. export controls imposed since 2022, which require the South Korean chipmakers to seek annual licenses for U.S.-made equipment, according to the Commerce Department's Bureau of Industry and Security.
  • Yangtze Memory Technologies captured 38.5% of China's NAND market in the second quarter, up from 28% in 2025, while Samsung's share fell to 33.5% from 36% and SK Hynix's dropped to 17% from 20%, according to research firm Omdia.
  • Samsung is converting its Xian plant to manufacture 286-layer V9 NAND chips, targeting 5,000 wafers monthly by December this year and 40,000 by December 2027, while SK Hynix plans to shift its Dalian facilities to 240-layer production.
  • Separately, SK Hynix is in discussions with the Trump administration regarding plans to build a new NAND factory in the United States, potentially leveraging research from its Solidigm business unit acquired from Intel in 2021.
