Abstract

The disclosed technology generally relates semiconductor devices, and relates more particularly to a spin transfer torque device, a method of operating the spin-transfer torque device and a method of fabricating the spin-transfer torque device. According to one aspect, a spin-transfer torque device includes a magnetic flux guide layer and a set of magnetic tunnel junction (MTJ) pillars arranged above the magnetic flux guide layer. Each one of the pillars includes a separate free layer, a separate tunnel barrier layer and a separate reference layer. A coupling layer is arranged between the magnetic flux guide layer and the MTJ pillars, wherein a magnetization of the separate free layer of each of the each of the MTJ pillars is coupled, parallel or antiparallel, to a magnetization of the magnetic flux guide layer through the coupling layer.
