SRAM: Dead or Alive?

By Kauser Johar, Chipletti

Is SRAM Dead or Just Evolving? SRAM has powered CPU caches for decades, but its scaling has stalled—raising questions about its future. This talk explores SRAM’s origins, its rise in computing, and the limits of current scaling. We’ll introduce 3D chiplets as a path forward, highlight key break-even points in area, cost, and performance, and show how 3D SRAM can unlock next-generation AI inference, including trillion-parameter models. Far from obsolete, SRAM may be poised for a 3D-powered comeback.
