Two giants, Samsung and SK hynix, make most of the world's memory, and the AI boom has made high-bandwidth memory (HBM) the hottest product in the industry. A deep supply chain of equipment and materials makers sits around them south of Seoul.
Samsung Electronics' Device Solutions division (memory, foundry and System LSI) and SK hynix are the centre of gravity. SK hynix leads in HBM for AI accelerators, and both companies paid record bonuses in 2025 and 2026 as memory demand surged.
Most fabs are in Gyeonggi province: Hwaseong, Pyeongtaek, Giheung and Icheon, with a huge new cluster under construction in Yongin. Fabless design is smaller than in Taiwan but growing, led by display-driver and automotive chip companies.
Work is mostly in Korean. Global hiring exists, especially for PhDs and experienced specialists, and Samsung runs R&D centres abroad, including in India, that are often an easier first step.

Yes, mainly through global recruiting for experienced engineers and PhDs, and through graduates of Korean universities. Korean language skills make a big difference for most roles.
High-bandwidth memory stacks DRAM dies for AI accelerators. Demand has exploded, so memory design, packaging and test roles are in short supply.
Yes, though fewer than in Taiwan. LX Semicon, Telechips and AI-chip startups such as Rebellions and FuriosaAI hire design and verification engineers.
