Researchers build room-temperature memory that doesn’t need a current to retain data

All modern computer memory works on basically the same principle — an electrical current is used to change the charge state of a cell. That charge state is then “read” by the memory controller. Whether we’re talking about NAND flash or RAM, this basic property is identical between them. Now, researchers at Cornell have announced and demonstrated a device based on bismuth ferrite that can store data and retrieve datawithout needing an electrical current to do so. The implications of such a room-temperature breakthrough could be profound — a long time from now.
