1. A magnetic tunnel junction cell comprising: a first ferromagnetic pinned layer, a ferromagnetic free layer, and a non-magnetic barrier layer therebetween, the first pinned layer and the free layer each having an out-of-plane magnetization orientation, a second ferromagnetic pinned layer and a coupling layer between the second pinned layer and the free layer, the coupling layer comprising a phase change material switchable between an antiferromagnetic state to a ferromagnetic state.
