Micron Phase Change Memory for Mobile Devices Now Available

Is this for real? Does anyone have any insight into this?

Looks interesting. Hopefully this is the first in a long line of flash-killers. Several places seem to confirm, but it will likely be a while until we see products made from it.

For older devices (looks like 90nm process):The VCC is a little high, at ~3V, but the highest current draw I could see is 51mA, not too bad.

http://www.micron.com/~/media/Documents ... pcm_ds.pdf

for a parallel, 128Mb chip. To give a 1TB memory module, you would need a square 3 meters on a side with both sides covered with these. Read cycle time is 135ns, or between a factor of 4 and 10 slower than DDR3 RAM (depending on how you define read cycle time). Still pretty fast.

New chips mentioned here: http://investors.micron.com/releasedeta ... eID=692563

Hopefully the newer chips have higher densities and faster speeds. And are cheap. But as with many better, faster, cheaper, you usually have to pick only two.

They claim it is available, today, in large volumes. This time it seems to look real.

The chips themselves are, the SSD's and such like built from them are likely a year or more off. Companies that use the chips for storage and memory will have to build test devices first to evaluate performance, etc, before selling things to the public.

Eve if it is a year out, more competition is always welcomed.

I've lost confidence in Micron after my ram failure rate hit the roof with crucial ram in the last few years both normal and premium memory. Worse, I found their customer support bordering awful they took weeks to replace some modules, rather than apologise they made excuses.
The technology looks intersting, but more so if someone else runs with it not micron!
