China’s new chip stores data with a single electron, breaking AI memory bottleneck
The News
A team at Fudan University in Shanghai, led by microelectronics professor Zhou Peng, has developed a new chip that stores a single bit of information using just one electron, a dramatic reduction from the 200,000 electrons used in current DRAM chips from Samsung and SK Hynix. The breakthrough, published in Science on July 16, could potentially overcome the memory bottleneck in AI systems by drastically reducing power consumption and increasing storage density.

Plain English
Loaded language removedHow many electrons does it take to store a single bit of information? For today’s most advanced dynamic random access memory (DRAM) chips from Samsung and SK Hynix, the answer is roughly 200,000. That is the price of reliability – a vast reservoir of charge needed to ensure a “1” or “0” does not fade into noise.
