A Stealth Startup Thinks It Just Hacked the Memory Shortage
Startup Kepler Computing has emerged from stealth mode with a new 3D-stacking memory architecture designed to bypass the need for expensive EUV lithography. The company has secured significant funding and government support to address global memory-chip shortages.
Why it matters
If successful, this technology could lower production costs and increase supply for high-performance AI memory, impacting the broader semiconductor industry.
An ambitious chip startup that has spent more than seven years quietly trying to redesign the architecture for computer memory has just come out of stealth mode and believes its new approach can help ease the global memory-chip shortage—provided it can produce its technology at scale.
Kepler Computing, a San Jose, California–based startup founded in 2018 by a team of physicists and computer scientists, says it has developed a new architecture for high-bandwidth memory (HBM) that directly addresses some of the chip supply bottlenecks that are constraining the computing market.
While chipmakers typically rely on expensive extreme ultraviolet lithography (EUV) to shrink the transistors on a chip, thereby packing more technology into the same amount of space, Kepler claims that its “3D stacking” approach and a proprietary new material allow it to increase density without relying on EUV at all—and it can work with existing semiconductor fabrication plants.
