HEATING PHASE CHANGE MATERIAL

摘要

A phase change memory may be formed of two vertically spaced layers of phase change material. An intervening dielectric may space the layers from one another along a substantial portion of their lateral extent. An opening may be provided in the intervening dielectric to allow the phase change layers to approach one another more closely. As a result, current density may be increased at this location, producing heating.

主权项

1. A system comprising:
a controller; a wireless interface coupled to said controller; and a phase change memory, coupled to said controller, said phase change memory including first and second chalcogenide materials, said first and second chalcogenide materials being spaced from one another by an intervening layer, an opening through said intervening layer to reduce the space in between said first and second chalcogenide materials.
