Title:
HEATING PHASE CHANGE MATERIAL
Document Type and Number:
WIPO Patent Application WO2006110518
Kind Code:
A3
Abstract:
A phase change memory is formed of two vertically spaced layers (18, 34) of phase change material. An intervening dielectric (20) spaces the layers from one another along a substantial portion of their lateral extent. An opening (28) is 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.
