SK Hynix will invest 54 trillion won ($38 billion) to expand South Korean chipmaking facilities through 2031. The company's board approved the plan to meet surging demand for artificial intelligence memory chips.
The plan allocates 35.2 trillion won for a new DRAM fabrication plant in Yongin. Another 19.1 trillion won will fund a NAND facility in Cheongju.
The Yongin plant will produce high-bandwidth memory (HBM) and next-generation DRAM. Construction in Yongin begins in July 2027, with the first cleanroom opening in June 2029. Cheongju construction starts in February 2027, with a cleanroom opening scheduled for December 2028.
