Abstract:
A non-volatile current-switching magnetic memory element includes a bottom electrode, a pinning layer formed on top of the bottom electrode, and a fixed layer formed on top of the pinning layer. The memory element further includes a tunnel layer formed on top of the pinning layer, a first free layer formed on top of the tunnel layer, a granular film layer formed on top of the first free layer, a second free layer formed on top of the granular film layer, a cap layer formed on top of the second free layer, and a top electrode formed on top of the cap layer.
