Claim Text:
1. A magnetic tunnel junction device comprising: a first magnetic tunnel junction (MTJ) element comprising a first top ferromagnet layer formed of a first magnetic material; a first tunneling layer; and a bottom ferromagnet layer formed of a second magnetic material, wherein the first tunneling layer is mounted between the first top ferromagnet layer and the bottom ferromagnet layer; a second MTJ element comprising; a second top ferromagnet layer formed of a third magnetic material; a second tunneling layer; and the bottom ferromagnet layer, wherein the second tunneling layer is mounted between the second top ferromagnet layer and the bottom ferromagnet layer; and a single control wire configured to conduct a charge pulse to generate a magnetic field, wherein a direction of charge flow in the single control wire extends substantially perpendicular to a magnetization direction of the first top ferromagnet layer and of the second top ferromagnet layer, wherein the direction of charge flow in the single control wire extends between the first top ferromagnet layer and the second top ferromagnet layer, wherein the single control wire is positioned sufficiently close to the first top ferromagnet layer and to the second top ferromagnet layer to reverse the magnetization direction of the first top ferromagnet layer and of the second top ferromagnet layer solely via the magnetic field when the charge pulse flows therethrough while not reversing the magnetization direction of the bottom ferromagnet layer via the magnetic field when the charge pulse flows therethrough, wherein the first MTJ element has a first side surface extending perpendicular to a first plane defined by the first top ferromagnet layer, further wherein the second MTJ element has a second side surface extending perpendicular to a second plane defined by the second top ferromagnet layer and facing towards the first side surface, and further wherein the single control wire extends between the first and second side surfaces and alongside the first and second side surfaces.
