Forming phase change memories
View Patent ↗Phase change memories may exhibit improved properties and lower cost in some cases by forming the phase change material layers in a planar configuration. A heater may be provided below the phase change material layers to appropriately heat the material to induce the phase changes. The heater may be coupled to an appropriate conductor.
1. A system comprising:
a phase change memory including a planar phase change layer over a heater and a conductor, said conductor electrically coupled to said heater and said heater physically coupled to said planar phase change layer;
an insulator around said heater and under said planar phase change layer;
a glue layer between said planar phase change layer and said insulator, to secure said planar phase change layer to said insulator; and
a digital signal processor coupled to said memory.
2. The system of claim 1 wherein said planar phase change layer is over a carbon containing layer.
3. The system of claim 2 wherein said carbon containing layer is planar.
