Micron Maps AI Memory Roadmap: HBM4 Hits 2.6x Gains [2026] - shattered.io

Micron's latest AI memory roadmap points to HBM4 delivering a 2.6x gain, with 2026 as the target window. The headline doesn't specify the metric, so buyers should wait for Micron's detailed specs before building that figure into capacity or performance models. HBM mostly reaches buyers through accelerator platforms, but roadmap moves like this tend to shape supply and allocation across the broader server memory market, including DDR5, MRDIMM, and RDIMM for host systems.
