Super Fast Memory To Replace Hard Drives?
Tuesday, December 12th, 2006
IBM, Qimonda and Macronix have discovered new technology that allows memory chips to work faster while consuming less power. This new invention makes use of the PCM memory cards and is made from of a type of semiconductor alloy.
The new material makes “phase-change” memory 500 to 1,000 times faster than “flash” memory utilizing half as much power.
This new breakthrough would allow mobile computers to replace fragile hard drive units with the new PCM cards.
Phase-change memory basically uses an alloy that can be swapped between an ordered crystalline phase and disordered amorphous phase. No power is needed to maintain a phase so this type of memory is non-volatile - this means that no data will be lost when you power down your machine.
This would take mobile computing to a whole new level I would think.
