SK Hynix Pulls Forward Yongin Fab to Feb. 2027, Sets HBM Wafer Starts in Cheongju Next Month

Exploding AI server demand is reshaping memory supply, with customers shifting to multi‑year deals as prices stay elevated.

Overview

  • SK Hynix will open the first factory at its new Yongin complex three months early in February 2027, according to executive Sungsoo Ryu.
  • The company plans to begin deploying wafers next month at the M15X fab in Cheongju to produce high‑bandwidth memory used in AI systems from Nvidia and AMD.
  • SK Hynix is investing about 19 trillion won in a new HBM‑focused facility in Cheongju, with advanced packaging capacity intended for AI data centers rather than consumer RAM.
  • Hyperscale customers are moving from one‑year contracts to multi‑year supply agreements to secure long‑term memory capacity.
  • TrendForce data show some memory products rose more than 300% year on year in Q4, and SK Hynix says it will maintain consumer channels even as tight supply keeps the market under pressure.
