Abstract

The invention relates to a novel memory cell structure and process to fabricate chalcogenide phase change memory. More particularly, it produces a small cross-sectional area of a chalcogenide-electrode contact part of the phase change memory, which affects the current/power requirement of the chalcogenide memory. Particular aspects of the present invention are described in the claims, specification and drawings.
