A phase change memory (PCM) cell includes a first electrode comprised of a first electrically conductive material, a second electrode comprised of a second electrically conductive material, and a phase change section positioned between the first electrode and the second electrode. The phase change section includes a first phase change material having a first resistance drift coefficient, and a second phase change material having a second resistance drift coefficient that is greater than the first resistance drift coefficient. An axis of the PCM cell extends between the first electrode and the second electrode, and the second phase change material is offset from the first phase change material in a direction that is perpendicular to the axis.
