Abstract: Spin torque transfer magnetic random access memory devices configured to be programmed unidirectionally and methods of programming such devices. The devices include memory cells having two pinned layers and a free layer therebetween. By utilizing two pinned layers, the spin torque effect on the free layer from each of the two pinned layers, respectively, allows the memory cells to be programmed with unidirectional currents.

Abstract: A magnetic cell structure including a nonmagnetic bridge, and methods of fabricating the structure are provided. The magnetic cell structure includes a free layer, a pinned layer, and a nonmagnetic bridge electrically connecting the free layer and the pinned layer. The shape and/or configuration of the nonmagnetic bridge directs a programming current through the magnetic cell structure such that the cross sectional area of the programming current in the free layer of the structure is less than the cross section of the structure. The decrease in the cross sectional area of the programming current in the free layer enables a lower programming current to reach a critical switching current density in the free layer and switch the magnetization of the free layer, programming the magnetic cell.
