With these two papers the team reported research on novel resistive memory devices based on perovskite quantum wires. The devices demonstrate the world fastest switching speed of 100 pico seconds among all kinds of RRAMs, with a long retention time (up to 20 years by extrapolation of life time test data). In other words, it can save an one Giga byte size movie video file in the memory with one second, if the peripheral circuit can also support this speed. The technology developed in these works may find broad applications in large volume data storage, high speed computing and neuromorphic computing in the future. The first authors of the two papers are PhD students Miss. Yuting ZHANG and Mr. Swapnadeep PODDAR supervised by Prof. FAN.
