Abstract
A bottom electrode, a phase change material layer, the phase change material layer includes a similar lattice constant as a lattice constant of the bottom electrode, and a top electrode vertically aligned. A phase change material layer, a top electrode adjacent to a first vertical side surface of the phase change material layer, and a bottom electrode adjacent to a second vertical side surface of the phase change material layer. Forming a phase change material layer, forming a top electrode adjacent to a first vertical side surface and overlapping a first portion of an upper horizontal surface of the phase change material layer, forming a bottom electrode, adjacent to a second vertical side surface and overlapping a second portion of the upper horizontal surface of the phase change material layer, and forming a dielectric material horizontally isolating the bottom electrode and the top electrode.
