Advance In PCM Memory Could Dramatically Reduce Power Consumption 74

Zothecula writes "Researchers from the Electrical and Computer Engineering Department of the University of Illinois have developed new low-power digital memory which uses much less power and is faster than other solutions currently available. The breakthrough could give future consumer devices like smartphones and laptops a much longer battery life, but might also benefit equipment used in telecommunications, science or by the military."

    uses much less power and is faster than other solutions currently available

    Haven't seen however any info on the speed.

    The researchers say that the low-power memory could even lead to previously elusive three-dimensional stacking of chips.

    This would be good indeed if achieved.
    Speaking of achievements, there's just this snag:

    The group has so far created and tested a few hundred bits

    On top of it:

    The device is also immune to accidental erasure from a passing scanner or magnet.

    This may well be, but... what range of temperatures is supported by the phase-change material? (i.e. what good is the low-power/high-speed memory if it melts when overclocking the CPU?)
