1. A device having:
a multilayer composite phase change material structure comprising:
a bottom SbTe PCM layer of a first PCM material having a first metallic doping;
a first composite PCM layer on the bottom PCM layer, wherein the first composite PCM layer comprises at least:
a first composite layer, comprising said first PCM material having a second metallic doping; and
a second composite layer, comprising said first SbTe PCM material undoped, on the first composite layer; and
a top PCM layer, comprising first SbTe PCM material having said first metallic doping, on the composite PCM layer.
