Microchip development has always been a race to build smaller and smaller transistors – the fundamental components of chip circuits. Now China’s Huawei Technologies wants to change the game entirely. Faced with US tech export restrictions that block its access to the world’s most advanced chipmaking machinery, Huawei is proposing a fundamental shift in semiconductor progress: stop obsessing over how small the transistors are and start focusing on how fast data moves through the system. It is a...
