Spin transfer torque memory (STTM) device with half-metal and method to write and read the device

摘要

Spin transfer torque memory (STTM) devices with half-metals and methods to write and read the devices are described. For example, a magnetic tunneling junction includes a free magnetic layer, a fixed magnetic layer, and a dielectric layer disposed between the free magnetic layer and the fixed magnetic layer. One or both of the free magnetic layer and the fixed magnetic layer includes a half-metal material at an interface with the dielectric layer.
