Samsung, SK Hynix aim to ease AI memory bottlenecks with zHBM, HBF

What happened

Samsung Electronics and SK Hynix are developing new memory technologies to address growing bottlenecks in AI systems. Samsung is exploring a design that stacks high-bandwidth memory (HBM) directly above graphics processors (zHBM), while SK Hynix is advancing high-bandwidth flash (HBF) to expand memory capacity for AI inference. Both remain at the development/exploration stage; the source does not state timelines or production plans.
