摘要

In May, researchers at Hewlett-Packard (HP) unveiled their long-anticipated "mem-ristor," a device only a few nanometers wide that could revolutionize computer memory and help researchers build a machine that functions like a human brain. For decades, the memristor-short for memory resistor-had been little more than an engineer's dream: a circuit element with high-density memory and low energy requirements. The dream dated back to 1971, when electrical engineer Leon Chua described a theoretical fourth circuit element that would function along with the traditional trio of resistor, inductor, and capacitor. Unlike those other circuit components (and modern transistors), the memristor could retain information even after the current shuts off. In theory, a memristor-driven computer could boot instantly and have a much smaller power demand than current machines.
