Ed Doller, CTO of Numonyx, said that the chalcogenide used in phase-change memory is sensitive to temperatures above 150 degrees C, which means that above these temperatures data in a phase-change memory cell will be lost. System designers have had to adjust to this temperature limitation by programming data or code onto the phase-change memory chip after it has been assembled on a printed circuit board--a process that requires temperatures around 200 degrees C.

Reading the data takes comparatively no energy? Less than what Flash takes? 2,500 patents and 1,000 more, pending? Sheesh! Rate this comment: (Reply)
