Abstract

A magnetic memory cell includes: a first spin-orbit interaction active layer; a first magnetic free layer on the first spin-orbit interaction active layer, the first magnetic free layer having a changeable magnetization; a first nonmagnetic spacer layer on the first magnetic free layer; a reference layer having a fixed magnetization on the first nonmagnetic spacer layer; a second nonmagnetic spacer layer on the reference layer; a second magnetic free layer on the second nonmagnetic spacer layer, the second magnetic free layer having a changeable magnetization; and a second spin-orbit interaction active layer on the second magnetic free layer.
