Abstract
Techniques and magnetic devices associated with a magnetic element are described that includes a presetting fixed layer having a presetting fixed layer magnetization, a free layer having a changeable free layer magnetization, and a fixed layer having a fixed layer magnetization, where a presetting current pulse applied between the presetting fixed layer and free layer operates to preset the free layer magnetization in advance of a write pulse. Techniques and magnetic devices associated with a magnetic element are described that includes a first terminal, a first magnetic tunnel junction, a second terminal, a second magnetic tunnel junction, and a third terminal, where a current pulse applied between the first and second terminal operate to switch the state of the first magnetic tunnel junction and a current applied between the second and third terminal operate to switch the state of the second magnetic tunnel junction.
