Abstract:
One embodiment of the present invention includes a non-uniform switching based non-volatile magnetic memory element including a fixed layer, a barrier layer formed on top of the fixed layer, a first free layer formed on top of the barrier layer, a non-uniform switching layer (NSL) formed on top of the first free layer, and a second free layer formed on top of the non-uniform switching layer, wherein switching current is applied, in a direction that is substantially perpendicular to the fixed, barrier, first free, non-uniform and the second free layers causing switching between states of the first, second free and non-uniform layers with substantially reduced switching current.
