SK Hynix approved 54 trillion won ($38 billion) in investments on Friday, authorizing construction of two new fabrication plants on home soil — one for DRAM and one for NAND flash — as AI-driven appetite for memory chips shows no sign of slowing.

The board earmarked 35.2 trillion won for the Yongin facility, known as Y2, and 19.1 trillion won for a second plant in Cheongju, designated M17, the company said. Y2 is set to begin construction in July 2027, with the facility's first cleanroom expected to come online in June 2029, focused on high-bandwidth memory and other advanced DRAM products. The Cheongju M17 fab will break ground in February 2027, with its first cleanroom set to open in December 2028.
