YorChip announces Universal PHY™ PPA and introduces Open PHY to jumpstart broader market

Universal PHY™ is designed for both logic and memory over UCIe. The PHY cell supports TX, RX and switches modes rapidly a feature critical for HBM & HBF.

SAN RAMON, CA, UNITED STATES, October 27, 2025 -- YorChip, Inc. today announced the design completion of its Universal PHY, enabling customers to develop Open Chiplets and ASIC solutions for low power, cost-sensitive markets. The fully digital PHY, based on the UCIe-3D architecture, delivers power consumption below 0.1 pj/bit and area footprint of 0.07 mm2. The initial version targets digital logic interconnects – but the Universal PHY is designed to support future memory interfaces such as HBM over UCIe, HBF over UCIe and advanced NVM over UCIe applications.

The company also introduced a free Open PHY specification, which is interoperable with the Universal PHY™ for universities, inventors, and startups to accelerate Chiplet innovation. The Open PHY is suitable for mature nodes as well as specialty Optical, Memory and Mems nodes to join the multi-die revolution in a single package.

YorChip’s CEO and co-founder, Kash Johal, said “YorChip supports the Open Chiplet Economy initiative from OCP with our OpenPHY. Broad use of Chiplets is not happening due to PHY licensing costs (millions of dollars), lack of availability on mature nodes and OpenPHY will help jumpstart Chiplet adoption by eliminating cost and design barriers.”

YorChip’s CTO and co-founder, Frank Dunlap, said, “Universal PHY™ offers best in class Power and Area and is designed to support in-package connectivity for both logic and memory over UCIe. Our core PHY cell may be configured as either TX, RX and switches modes rapidly, a feature critical for future HBM, HBF and NVM applications which require asymmetric bandwidth.”

“Open chiplet architectures are redefining how innovation scales by enabling seamless die-to-die interoperability and lowering barriers to entry. QuickLogic is committed to accelerating this future by developing flexible, low-power interfaces and working hand-in-hand with partners like YorChip to make the Open Chiplet Economy a reality,” said Brian Faith, CEO of QuickLogic.
