Compute Moves Into Memory
Projection: Micron’s HBM4 widens the interface and raises bandwidth; the OpenAI-Broadcom accelerator explicitly co-designs memory movement with LLM serving. Selected operations may migrate into or beside memory arrays. The forecast requires net gains after precision limits, programmability, thermal behavior, and data still moving elsewhere are included.
Why this idea is here
What the evidence establishes.
Micron documents HBM4 with a wider interface, higher per-stack bandwidth, improved efficiency, and 2026 sampling and ramp milestones; OpenAI and Broadcom announce a custom inference accelerator co-designed around LLM kernels, memory movement, networking, and serving patterns. These are source-backed premises for this projection; they do not by themselves prove broad adoption or the eventual outcome.
