China’s Huawei unveils new sanctions-busting chip architecture that replaces Moore’s Law
Huawei unveiled a new chip architecture called LogicFolding, based on its Tau Scaling Law, to bypass U.S. sanctions and compete with Western semiconductor leaders by 2031. The design aims for 1.4-nanometer-class chips and a 55% increase in transistor density through temporal scaling and circuit stacking, debuting commercially in the Kirin processor for the Mate 90 smartphone later this year.
Huawei Technologies Co. Ltd. introduced a breakthrough chip design framework at the IEEE International Symposium on Circuits and Systems in Shanghai, marking a shift from Moore’s Law to its proprietary Tau Scaling Law. The company’s HiSilicon division, led by board member He Tingbo, revealed LogicFolding, a dual-layer architecture that folds and stacks logic circuits to reduce signal delay. Over six years, Huawei secretly designed 381 chips using this method, validating its principles before its commercial debut in the Kirin processor for the upcoming Mate 90 smartphone this autumn. The new approach prioritizes signal speed and data processing efficiency over transistor miniaturization, addressing U.S. sanctions that restrict China’s access to advanced EUV lithography machines. By 2031, Huawei claims its 1.4-nanometer-class chips will match Western performance, achieving a 55% increase in transistor density and a 41% boost in power efficiency. The architecture will also extend to Ascend AI processors, targeting high-capacity data centers by 2030 as an alternative to Nvidia’s GPUs. Traditional semiconductor scaling relies on shrinking transistor sizes, a method hindered by U.S. export controls. Huawei’s LogicFolding bypasses this limitation by optimizing internal wiring and circuit stacking, enabling competitive performance without reliance on restricted technology. The company’s efforts reflect China’s broader push to reduce dependence on foreign semiconductor supply chains, aligning with government initiatives to bolster domestic innovation. The Kirin processor’s release in the Mate 90 smartphone will serve as a test case for LogicFolding’s commercial viability. Huawei’s long-term goal is to scale the architecture across its product lineup, including AI infrastructure, positioning itself as a major player in global semiconductor competition. The announcement underscores China’s determination to advance its tech sector despite geopolitical constraints.
