Stealth startup Kepler Computing emerges to tackle memory shortage with 3D stacking
nordicinst · x · 2026-09-09
Kepler Computing, a San Jose startup founded in 2018, has exited stealth mode claiming a new HBM architecture that could ease the global memory shortage. Key points:
- Approach: Boosts density via "3D stacking" and a proprietary material — no EUV lithography needed, and it works with existing fabs.
- SRAM too: Claims similar gains for high-speed cache memory in CPUs, GPUs and XPUs.
- Funding: $468M raised from GlobalFoundries, Intel Capital, AMD Ventures, Baillie Gifford and Bill Gates.
Scaling the technology remains the big open question.
