History of Phase Change Memories

  • Chung H. Lam

Abstract

This chapter reviews the history of phase change materials particularly in the applications of information storage. The chapter starts with the discovery of a one way resistance transformation phenomenon in a chalcogenide, namely molybdenite (MoS2). Then the evolution of the understanding of the underlying physics governing the phase change characteristics by various investigators is reviewed along with the applications of the phase change characteristics in information storage applications. The chapter ends with a table summarizing critical events in the phase change memory developments.
