Patent ID: 8406041

Claim:
A method of writing to a magnetic memory cell comprising: providing a magnetic tunnel junction element adjacent to a first conductor line and means for current supply, the magnetic tunnel junction element comprising a pinned layer comprising a fixed magnetization direction directed substantially perpendicular to a film plane, a free layer comprising a reversible magnetization direction directed substantially perpendicular in its equilibrium state to the film plane, and a tunnel barrier layer residing between the pinned layer and the free layer; driving a bias current pulse through the first conductor line in a proximity to but not through the magnetic tunnel junction element and producing a bias magnetic field along a magnetic hard axis of the free layer; driving a spin-polarized current pulse through the tunnel magnetic junction element along a magnetic easy axis of the free layer, and producing a spin momentum transfer; whereby the magnetization direction in the free layer is reversed by a collective effect of the substantially superimposed pulses of the bias and spin-polarized currents.
