  • Semiconductor phast change memory using multiple phase change layers
    Patent number: 8223538
    Abstract: In accordance with some embodiments, a phase change memory may be formed in which the thermal conductivity in the region outside the programmed volume of phase change material is reduced. This may reduce the power consumption of the resulting phase change memory. The reduction in power consumption may be achieved by forming distinct layers of phase change material that have little or no mixing between them outside the programmed volume. For example, in one embodiment, a diffusion barrier layer may be maintained between the two distinct phase change layers. In another embodiment, a face centered cubic chalcogenide structure may be utilized.
