Micron Technology has commenced a $9.3 billion expansion of its Hiroshima plant in Japan, aiming to produce advanced storage chips, including high-bandwidth memory (HBM). This investment is part of a broader strategy to meet the growing demand driven by artificial intelligence advancements. The facility is expected to begin HBM shipments by the summer of 2028. HBM is a crucial component for NVIDIA's AI processors. This move follows similar capacity expansion announcements by Samsung Electronics and SK Hynix, with the latter planning a $51.5 billion investment in a new NAND chip plant in Cheongju, South Korea.
