Title: Staggered STRAM cell

Abstract: Spin-transfer torque memory having a free magnetic layer having a thickness extending in a out-of-plane direction and extending in a lateral direction in an in-plane direction between a first end portion and an opposing second end portion. A tunneling barrier separates a reference magnetic layer from the first end portion and forms a magnetic tunnel junction. A first electrode is in electrical communication with the reference magnetic layer and a second electrode is in electrical communication with the free magnetic layer second end portion such that current flows from the first electrode to the second electrode and passes through the free magnetic layer in the lateral direction to switch the magnetic tunnel junction between a high resistance state and a low resistance state.
