 Magnetic memory device using in-plane current and electric field patent thumbnailMagnetic memory device using in-plane current and electric field
Provided is a magnetic memory device for applying an in-plane current to a conductive wire adjacent to a free magnetic layer having a perpendicular magnetic anisotropy to induce a flux reversal of the free magnetic layer and simultaneously applying a voltage to each magnetic tunnel junction cell selectively to reverse magnetization of the free magnetic layer selectively at each specific voltage. The magnetic memory device may implement high density integration by reducing a volume since a spin-hall spin-torque causing a flux reversal is generated at an interface of the conductive wire and the free magnetic layer, ensure thermal stability by enhancing perpendicular magnetic anisotropy of the magnetic layer, and reduce a critical current density by increasing an amount of spin current.
