If data could instead be encoded without current it would require much less energy, and make things like low-power, instant-on computing a ubiquitous reality. Researchers have 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.
