Abstract:
A memory device includes: a first conductive column structure extending through a first dielectric layer, wherein the first conductive column structure comprises a shell portion wrapping a core structure filled with a dielectric material and an end portion that is coupled to one end of the shell portion and disposed below the core structure; and a first phase change material layer formed over the first dielectric layer, wherein a lower boundary of the first phase change material layer contacts at least a first portion of the other end of the shell portion of the first conductive column structure.

Claim (Index 19):
The method of  claim 18 , further comprising:\n forming a second dielectric layer over the phase change material layer; forming a second void extending through the second dielectric layer to expose a portion of an upper boundary of the phase change material layer; forming a second conductive structure lining along respective sidewalls of the second void and the exposed portion of the upper boundary of the phase change material layer to cause the phase change material layer to contact at least a portion of a sidewall and a bottom portion of the second conductive structure; filling the second void with the second dielectric layer; and forming a top electrode over the second dielectric layer to contact the second conductive structure.
