Flash memory to be replaced by phase-change memory?

A team of fair-haired boys from IBM, Macronix, and Qimonda have come up with a new type of non-volatile memory that is 500-1000 times faster than flash memory while consuming half the power, according to this Yahoo News story.

The new memory is based on phase-change technology (similar to that employed in recordable CDs and DVDs).  It employs a complex new semiconductor alloy that is the result of collaborative research at IBM's Almaden Research Center.

IBM's VP of Technology, T.C. Chen remarked "These results dramatically demonstrate that phase-change memory has a very bright future.  Many expect flash memory to encounter significant scaling limitations in the near future. Today we unveil a new phase-change memory material that has high performance even in an extremely small volume."

The research details were to be presented to engineers gathered at the 2006 International Electronic Devices Meeting in San Francisco.
