HBM & AI chips

The HBM and AI chip theme covers Korean companies that make high-bandwidth memory (HBM), a stacked DRAM design used alongside AI accelerators, as well as firms working on AI-focused semiconductors and related packaging and equipment. Korean investors tend to group these companies together because the memory makers are central suppliers to global AI data-center buildouts, so their fortunes are often discussed in relation to one another and to demand for advanced chips.
