SK hynix Commits 100 Trillion Won to Cheongju, Anchored by an 80 Trillion Won M17 NAND Fab, as Korea Doubles Down on AI Memory
SK hynix will spend 100 trillion won ($64.38 billion) on a new NAND fab and advanced packaging plant in Cheongju, part of a 392 trillion won Chungcheong buildout with Samsung.
Overview
SK hynix said on July 2 that it will invest 100 trillion won ($64.38 billion) to build new memory chip plants in the central South Korean city of Cheongju, according to Reuters. The commitment pairs a new NAND flash fabrication plant with an advanced packaging facility, and forms one half of a coordinated buildout with Samsung Electronics that South Korea is presenting as a national bid to hold its lead in AI-era memory.
What We Know
The headline project is a NAND flash factory known as M17. SK hynix will spend 80 trillion won on the plant, which is scheduled to break ground next year and is targeted to begin operations in the first half of 2029, according to The Korea Times. The remaining 20 trillion won will go toward advanced packaging facilities, including a plant called P&T7, with the packaging investment slated for completion by late 2027, as reported by Reuters.
The plans were announced by SK hynix President and Chief Executive Kwak Noh-jung at the National Briefing on the Vision for Advanced Industry Development in the Chungcheong Region, according to TrendForce. Kwak framed the expansion as a response to a supply squeeze, saying that “While demand for NAND has been increasing and is expected to continue growing in the future, NAND supply is constrained,” as quoted by Reuters. He also pointed to the site itself, calling Cheongju “the company’s most suitable location for rapidly and efficiently constructing a new NAND fabrication plant,” according to The Korea Times.
SK hynix’s pledge is coordinated with a parallel commitment from Samsung, which announced a total of 140 trillion won in investment in Chungcheong Province, according to The Korea Times. Samsung’s plan includes 56 trillion won for high-bandwidth memory fabrication in Onyang and Cheonan, according to TrendForce. Combined with existing projects, an industrywide 392 trillion-won ($252.5 billion) investment will be injected into the central Chungcheong area, and the package is a follow-up to the government’s tripolar mega projects unveiled by President Lee Jae Myung earlier in the week, according to The Korea Times.
The scale of the push reflects a broader national goal: South Korea is hoping the investments will double the country’s memory chip production capacity within five years, according to Reuters.
Why It Matters
The Cheongju commitment underscores how sharply AI demand has redrawn memory-industry priorities. NAND flash — the non-volatile storage used in SSDs and increasingly in AI infrastructure — has become a fresh capacity battleground alongside the high-bandwidth memory that has driven the current supercycle. TrendForce notes that the growing adoption of agentic AI and physical AI is broadening NAND flash applications, making further capacity expansion necessary, according to TrendForce.
Politically, the buildout is a win for President Lee Jae Myung, who wants the AI windfall to help revive economies beyond the Seoul metropolitan area, according to Reuters. By concentrating fabs and packaging plants in Chungcheong, the plan aims to spread the returns of the memory boom into a region outside the capital.
What We Don’t Know
The multi-year timelines leave the payoff exposed to a shifting demand picture. Reuters reports that the plans could change depending on global chip demand, and that the aggressive capacity buildout has stoked concerns about a painful reckoning if AI spending cools, according to Reuters. With the M17 fab not due to begin operations until the first half of 2029, the wager is that AI-driven demand for NAND and advanced packaging will still be climbing when the new capacity comes online.
