Spin-Transfer Torque MRAMs for Low Power Memories: Perspective and Prospective

Electron-spin based data storage for on-chip memories has the potential for ultrahigh density, low power consumption, very high endurance, and reasonably low read/write latency. In this article, we analyze the energy-performance characteristics of a state-of-the-art spin-transfer-torque based magnetic random access memories (STT-MRAM) bit-cell in the presence of parametric process variations. In o...
