Fudan University Achieves Single-Electron Data Storage Breakthrough
Hızlı Bakış
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.

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.
