SK Hynix expects the global market for high-bandwidth memory (HBM) used in artificial-intelligence systems to expand about 30% a year through 2030, according to Choi Joon-yong, who heads the South Korean chipmaker’s HBM business planning unit. In an interview with Reuters, Choi said sustained investment in AI infrastructure by cloud providers such as Amazon, Microsoft and Alphabet’s Google should lift demand for the high-performance chips, driving the segment’s value into the ‘tens of billions of dollars’ within five years. The vertically stacked HBM devices help cut power use while processing the large data sets required by generative-AI models and are a critical component in Nvidia’s latest accelerators, for which SK Hynix is the primary supplier. Choi added that future growth could accelerate further as customers request increasingly customised versions of the memory, deepening the link between AI build-outs and HBM orders.
