Memory Details

Micron’s newly unveiled memory and storage product HBM4 is designed to offer much faster data speeds, higher capacity, and better power efficiency than the previous generation, the company said.

The latest HBM4 will deliver more than 11 Gb/s pin speed, based on internal testing and confidential customer test vehicle validation, and over 2.8 TB/s bandwidth. This amounts to about 2.3 times higher than HBM3E with over 20% better power efficiency, the company said.

Taiwan Site

Earlier on Monday, the company announced that it plans to build a second manufacturing facility in Taiwan at the Tongluo site it recently acquired from Powerchip Semiconductor Manufacturing Corp. in a bid to boost production of advanced DRAM chips, including high-bandwidth memory used in AI systems.

The site already includes about 300,000 square feet of 300mm cleanroom space, and the new facility will add roughly 270,000 square feet more, the company said.

Micron expects construction to begin by the end of fiscal 2026, with meaningful shipments from the existing fab starting in fiscal 2028.
