Abstract

See full text

A phase change memory (PCM) cell comprises a first electrode comprised of a first electrically conductive material, a second electrode comprised of a second electrically conductive material, a first phase change layer positioned between the first electrode and the second electrode and being comprised of a first phase change material, and a second phase change layer positioned between the first electrode and the second electrode and being comprised of a second phase change material. The first phase change material has a first resistivity, the second phase change material has a second resistivity, and wherein the first resistivity is at least two times the second resistivity.
