摘要: A memory unit having a spin torque memory cell with a ferromagnetic free layer, a ferromagnetic pinned layer and a spacer layer therebetween, with the free layer having a switchable magnetization orientation with a switching threshold. A DC current source is electrically connected to the spin torque memory cell to cause spin transfer torque in the free layer. An AC current source is electrically connected to the spin torque memory cell to produce an oscillatory polarized current capable of spin transfer torque via resonant coupling with the free layer.
