Instant-Start Computers Possible with New Breakthrough

If data could be encoded without current, it would require much less energy and make things like low-power, instant-on computing a ubiquitous reality. A team at Cornell University has made a breakthrough in that direction with a room-temperature magnetoelectric memory device. Equivalent to one computer bit, it exhibits the holy grail of next-generation nonvolatile memory: magnetic switchability, in two steps, with nothing but an electric field. Their results were published online Dec. 17 in Nature.
