Phase-changing memory looks great. It's supposed to combine the non-volatile nature of flash-based memory with the fantastic speed of DRAM. Now Intel and Numonyx are teasing with advancements in stacking memory layers, news that brings denser PCM closer to markets.
It's anticipated that PCM will initially be considered too pricey once it does in fact become available to consumers, but what product doesn't start off like that? Once prices level out and potential issues are sorted out though, it's predicted that phase-changing memory will kill off flash. Makes sense, since there's no reason to settle for a less dense product when you could have stacks of memory that's just as non-volatile after all. [Ars Technica]
