ABSTRACT:
A method and system for providing a magnetic element is described. The magnetic element includes a first pinned layer, a first spacer layer, a free layer, a second spacer layer, and a second pinned layer. The first and second pinned layers have first and magnetizations oriented in first and second directions, respectively. The first and second spacer layers are nonferromagnetic. The first and second spacer layers are between the free layer and the first and second pinned layers, respectively. The magnetic element is configured either to allow the free layer to be switched to each of multiple states when both a unidirectional write current is passed through the magnetic element and the magnetic element is subjected to a magnetic field corresponding to the each states or to allow the free layer to be switched to each of the plurality of states utilizing a write current and an additional magnetic field that is applied from at least one of the first pinned layer and the second pinned layer substantially only if the write current is also applied.
