SK hynix's M15 and M15X fabs in Cheongju; its M17 fab, on the same campus, is a row of its own. SK hynix wrote on 25 September 2024 that "In Cheongju, the company runs a fab called M15 which strengthens the company’s NAND flash business". Its release of 24 April 2024 says it will build M15X "for a new DRAM production base", and on 8 July 2026 it said M15X is being developed as "a production hub optimized for next-generation DRAM, such as HBM". On 29 October 2025 SK hynix reported that at M15X "equipment installation has recently begun after the early opening of a new cleanroom". No SK hynix page read for this row gives a year for first output at M15X. The row previously listed V-NAND alone.
