SK Hynix

SK Hynix is a South Korean semiconductor company and one of the world's largest producers of memory chips, specializing in DRAM, NAND flash, and high-bandwidth memory (HBM). Headquartered in Icheon, South Korea, it operates as a subsidiary of the SK Group conglomerate and competes directly with Samsung and Micron across the global memory market.

The company has become a central figure in the AI hardware boom, supplying the high-bandwidth memory chips that power AI accelerators used in data centers worldwide. HBM stacks multiple DRAM dies to deliver the extreme memory bandwidth that large-scale AI training and inference workloads demand, and SK Hynix has established itself as a leading supplier in this segment.

As AI investment accelerates, SK Hynix, Samsung, and Micron are engaged in an intensifying race to scale HBM capacity and advance each successive generation of the technology. South Korea's broader ambitions in AI—spanning chips, infrastructure, and software—make SK Hynix a bellwether for the country's semiconductor competitiveness on the global stage.
