Abstract
In some embodiments, the present disclosure relates to an integrated chip including a phase change material disposed over a bottom electrode and configured to change from a crystalline structure to an amorphous structure upon temperature changes. A top electrode is disposed over an upper surface of the phase change material. A via electrically contacts a top surface of the top electrode. Further, a maximum width of the upper surface of the phase change material is less than a maximum width of a bottom surface of the phase change material.
