Abstract :
Nonvolatile embedded memories may open the door to new computing paradigms based on "normally-off and instant-on" operation. This article covers recent trends of spin-transfer-torque RAM technology, an emerging class of nonvolatile memory, and discusses its impact on the different layers of computer system hierarchy.
