Micron

Micron broke ground on July 4 on a ¥1.5 trillion ($9.3 billion) expansion of its Hiroshima fab to scale next-generation DRAM and HBM for AI, with Japan's METI pledging up to ¥500 billion in subsidies and equipment installation set to begin in the second half of 2028.

Micron's 9650 NVMe SSD has entered mass production as the first PCIe Gen6 data center drive to ship at scale, with up to 28 GB/s reads and 5.5 million random read IOPS.

All three major memory chipmakers crossed $1 trillion in market cap within weeks as AI demand, sold-out HBM4 capacity, and a landmark UBS upgrade triggered a historic valuation surge.

Micron Technology posted record fiscal Q2 revenue of 23.9 billion dollars, nearly tripling year over year on surging AI memory demand, while guiding fiscal Q3 to 33.5 billion dollars -- a single quarter that would exceed its entire annual revenue through fiscal 2024.

Samsung, SK Hynix, and Micron have all confirmed high-volume HBM4 production for NVIDIA's Vera Rubin platform at GTC 2026, with 12-layer stacks delivering 2.8 TB/s bandwidth and 16-layer samples already shipping to customers.
