Patent attributes
A magnetoresistive memory element (e.g., a spin-torque magnetoresistive memory element) includes a fixed magnetic layer, a free magnetic layer having perpendicular magnetic anisotropy, and a first dielectric, disposed between the fixed magnetic layer and the free magnetic layer. A first surface of the first dielectric is in contact with a first surface of the free magnetic layer. The magnetoresistive memory element further includes a second dielectric, having a first surface that is in contact with a second surface of the free magnetic layer, a conductor, including electrically conductive material, and an electrode, disposed between the second dielectric and the conductor. The electrode includes: (i) a non-ferromagnetic portion having a surface that is in contact with a second surface of the second dielectric, and (ii) a second portion including at least one ferromagnetic material disposed between the non-ferromagnetic portion of the electrode and the conductor.
