Abstract:
Aspects of the present disclose related to a voltage-controlled magnetic anisotropy (VCMA) switching device using an external ferromagnetic biasing film. Aspects of the present disclose provide for a magnetoresistive random access memory (MRAM) device. The MRAM device generally includes a substrate, at least one magnetic tunnel junction (MTJ) stack disposed on the substrate, wherein the MTJ stack comprises a tunnel barrier layer between a first ferromagnetic layer having a fixed magnetization and a second ferromagnetic layer having unfixed magnetization, and a magnet disposed adjacent to the second ferromagnetic layer.
