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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Voltage-controlled magnetic anisotropy switching device using an external ferromagnetic biasing film","description":"Aspects of the present disclose related to a voltage-controlled magnetic anisotropy (VCMA) switching device using an external ferromagnetic biasing film.
