SK hynix is a South Korean company that makes memory chips. Its two main products are DRAM chips, which help computers and phones run multiple tasks at once, and NAND flash storage chips, which store data in devices like smartphones, laptops, and data center servers. It is one of the three largest memory chip makers in the world, alongside Samsung and Micron.

SK hynix earns money by selling these chips to large technology companies, including Apple, major PC makers, and cloud computing firms. It operates primarily out of South Korea, with manufacturing facilities there and in China. The memory chip industry is highly cyclical, meaning profits can swing sharply depending on supply and demand. A key growth driver is rising demand for high-bandwidth memory (HBM) chips used in artificial intelligence hardware, where SK hynix has been an early supplier to Nvidia — but the company remains exposed to sudden drops in chip prices if demand slows.
