Ferroelectric-Memory Startup Kepler Computing Exits Stealth With $468M to Sidestep EUV Bottleneck

San Jose-based Kepler Computing emerged from stealth on the back of $468M raised — including a $245M CHIPS Act award and backing from GlobalFoundries, Intel Capital, AMD Ventures and Bill Gates — pitching a 3D-heterogeneous-integration approach that stacks ferroelectric RAM tiles on top of logic chips to boost HBM/SRAM density without relying on EUV lithography. Kepler claims its process runs on existing fab equipment, positioning it against the AI-driven memory shortage.
