South Korea memory megacluster faces power and water bottlenecks

South Korea is trying to accelerate one of the world's largest semiconductor buildouts, with Samsung and SK hynix central to the plan. The program combines memory fabs, AI infrastructure, data centers, and robotics investment, making it a key part of the country's effort to defend its position in DRAM, NAND, and HBM. The limiting factor may not be cleanroom construction alone. Large memory campuses need utility capacity on the scale of major cities, and the available payload points to power delivery and water systems as the main schedule risks. If those inputs arrive later than fab shells and tools, new wafer output can be delayed even when capital spending remains aggressive. For RamTrend, the story is a medium-term supply risk. Utility bottlenecks would not change spot prices overnight, but they could slow the pace at which planned Korean memory capacity reaches volume production. That matters most for HBM and other AI-driven products, where demand is already competing for advanced manufacturing and packaging resources.
