Abstract:
1. A non-volatile current-switching magnetic memory element capable of storing information when current flows therethrough, comprising: a pinning layer; a first ferromagnetic layer formed on top of the pinning layer; a first synthetic anti-ferromagnetic coupling layer formed on top of the first ferromagnetic layer, the first synthetic anti-ferromagnetic coupling layer having a thickness; a second ferromagnetic layer formed on top of the first synthetic anti-ferromagnetic coupling layer; a tunnel layer formed on top of the second ferromagnetic layer; a free layer including, a top electrode formed on top of the magnetic coupling layers, wherein the thickness of the first synthetic anti-ferromagnetic coupling layer being greater than the thickness of each of the second synthetic anti-ferromagnetic coupling layer and third synthetic anti-ferromagnetic coupling layers.
