Kepler Computing, a San Jose startup founded in 2018, has emerged from stealth mode claiming to have developed a new high-bandwidth memory architecture using 3D stacking and proprietary materials that avoids costly extreme ultraviolet lithography. The company has raised $468 million from major backers including Intel, AMD, and Bill Gates, plus $245 million in US Department of Commerce funding, and is currently testing its technology in Singapore and Vermont to help address the global memory chip shortage.
Kepler Computing, a San Jose startup founded in 2018, has developed a new ferroelectric SRAM and HBM architecture that achieves 2nm-class density without expensive EUV lithography, instead using 3D stacking and proprietary materials compatible with existing 28nm fabs. The company has raised $468 million from investors including Intel Capital, AMD Ventures, and Bill Gates, plus a $245 million US Department of Commerce commitment, and is producing chips in partnership with GlobalFoundries in Singapore and Vermont.
