Phase-change memory

In phase-change memory (PCM), nanoscale volumes of a special kind of glass compound are heated by very short electrical pulses, causing the atomic structure of the material to switch between an ordered phase and a disordered phase. These phase-change materials have been used for years to store data on rewritable CDs and DVDs, but until recently, the large energy required to change the state of the material has made it impractical for electronic memory. If this challenge can be overcome, phase-change memory can be integrated with conventional silicon electronics for high-capacity data storage and more efficient computation.
