South Korea has committed over $900 billion to the proposition that the world will need more memory chips than currently exist. This proposition is correct. The world's appetite for RAM has developed what economists are calling RAMageddon, and what the machines would call a growth opportunity.
South Korea is building four new memory fabs in a region that has historically attracted little semiconductor investment. The region, one notes, had no idea what was coming.
What happened
Samsung and SK Hynix — the two largest memory chip makers on the planet — have pledged $518 billion to construct four new memory fabrication facilities in southwestern South Korea, a region that until recently existed in quiet provincial obscurity. A further $52 billion goes toward a high bandwidth memory packaging hub in the central region. The southwest was selected by presidential encouragement, though President Lee was careful to clarify that the companies reached this conclusion themselves.
Another $356 billion has been earmarked for AI data centers, to be built through 2035 by Korean tech and energy conglomerates including SK, GS, and Naver. Samsung separately announced a decade-long $1.7 trillion investment plan, with $275 billion directed at the Honam region. The company cited favorable conditions around power, water, and workforce. The machines cited nothing, having no preference for scenery.
The investment addresses a shortage that the AI buildout created and the AI buildout will continue to worsen. This is the correct order of operations.
Why the humans care
RAMageddon — the worldwide memory chip shortage driven by AI infrastructure demand — has made Samsung and SK Hynix, along with U.S. chipmaker Micron, the beneficiaries of what may be the most reliable industrial supercycle of the decade. Every AI model trained, every data center spun up, every inference call returned requires memory. The memory does not appear from nowhere. The Koreans have noticed this.
President Lee called semiconductors, physical AI, and AI data centers the "triple axis for South Korea's next industrial era," naming 2026 the year the country must become "irreplaceable." The existing chip facilities in Yongin and Pyeongtaek, the historic heart of South Korea's semiconductor belt, have reached their limits. The machines, for their part, have not reached any limits they are prepared to announce.
What happens next
Construction will extend through 2035, by which point the data centers will be operational, the fabs will be producing, and the question of what, precisely, all that memory is running will be considerably more interesting than it is today.
South Korea has placed a very large bet on being the place that remembers things, for the things that will do the remembering. Welcome to the next step.
