Claim 19:
20. A method comprising:
providing a bit cell device comprising a magnetic tunnel junction (MTJ) element and processing circuitry operatively coupled to the MTJ element, wherein the MTJ element includes a free layer structure, a free/pinned layer structure, and a tunnel barrier structure between the free layer structure and the free/pinned layer structure;
wherein a first electrode is coupled to the free layer structure and a second electrode is coupled to the free/pinned layer structure, the first electrode connected to a first node and a second node, the first node operative to receive a voltage from a voltage source, and the second node operative to receive a charge current from a current or voltage source;

applying a voltage to the MTJ element through the first node to modulate magnetic anisotropy in the free layer structure using an electric field, to enable writing with reduced write currents;
issuing a charge current to the MTJ element through the second node to induce spin-dependent writing and/or magnetic spin accumulation in the free layer structure to set a bit state of the MTJ element, using spin-transfer torque into the free layer structure; and
removing the voltage from the MTJ element that modulates the magnetic anisotropy, to perform a write operation.
