SK Hynix

SK Hynix, headquartered in Icheon, South Korea, is the world's second-largest manufacturer of dynamic random-access memory (DRAM) and NAND flash memory after Samsung Electronics. The company supplies HBM (High-Bandwidth Memory) stacks used in AI accelerators including NVIDIA's H100 and H200 GPUs, making it a pivotal supplier in the large-language-model infrastructure boom. SK Hynix's semiconductor research centre in Icheon employs thousands of engineers working on 4D NAND, next-generation DRAM scaling, and processing-in-memory architectures. The company funds academic semiconductor research through the SK Hynix-POSTECH Semiconductor Research Centre and bilateral agreements with KAIST, Seoul National University, and MIT. Joint publications address 3D NAND reliability, DRAM refresh power optimisation, and novel selector devices for cross-point memory arrays.
