Phase Change Memory: From Technological Challenges to Materials Science

Nonvolatile phase-change memory (PCM), which utilizes rapid and reversible electrothermal-induced phase transitions, is emerging as a key candidate for storage class memory to close the access-time gap between conventional memory and storage in computer systems. In this talk an alternative view on the phase transition mechanism of phase change memory will be proposed, starting from the octahedral structure motifs. Based on this mechanism, high performance phase change materials are developed for storage-class memory and embedded data storage applications.
