Phase Change Memory

webpronews.com:

Macronix, Infineon, and IBM are combining efforts to investigate the potential of a new kind of computer memory that may change the face of processing. It's called phase-change memory (PCM). Still in the early stages of development, researchers for the tech giants report that PCM uses a method of data storage that works by changing the state of special material from an amorphous structure to a crystalline structure instead of being stored as an electrical charge. All that technical jargon translates to the possibility of high-speed, high-density memory, working more similarly to the human brain, i.e., and electrically charged chemical soup that maintains data even when the power is turned off.

Way cool!
