Fudan University Achieves Single-Electron Data Storage Breakthrough
نظرة سريعة
Researchers at Fudan University in Shanghai have developed a device, named Guiyi, that can store a single bit of information using just one electron, a significant reduction from the 200,000 electrons required by current DRAM chips.

لماذا يهم
Current advanced dynamic random access memory (DRAM) chips from Samsung and SK Hynix require approximately 200,000 electrons to store a single bit of information for reliability.
How 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.
But a team at Fudan University in Shanghai has just collapsed that number to its theoretical floor: one.
The device, which they named Guiyi, lifts a faint, fleeting signal from just tens of millivolts to a robust 0.5 volts, a tenfold improvement over any previous single-electron attempt.
