RESET current around 150 uA, even at 22 nm will be stuck around 100 uA.

Very impressive achievement for Micron...I remember heated discussions just few years ago whether phase change memory will ever make it...I guess it did!

Stan Ovshinsky died on October 17th 2012. Energy Conversion Devices is at the tail-end of bankruptcy liquidation. Micron is buying the 1/3 of Ovonyx that ECD owned for 12 million. NOW Micron is producing PCM at a good pace. Dag-nabbit! I had missed Ron NEale's two articles on crystal electrodes that are linked in the "related information" box. (top-right) He seems to be learning more about the peculiar mechanisms in play. Micron's recent patents indicate that they are now a powerhouse in R&D. The world will benefit greatly from the fruits of their research. I do not expect Intel to let Micron run loose for much longer. Time will tell eh?

The so-called PCM is not in their spec.

Nokia Asha has more ROM than RAM, strange way to use PCM (not even mentioned still).

Not strange no PCM phones yet. Consuming more energy in shorter time means higher power consumption.

Hmm, Nokia must be out of their mind - paying their hard earned (and shall we say - scarce) cash for a technology that according to many forum-posters' (no less important and knowledeable people than that!) perceptions of strangeness :) /end sarcasm

If it is used merely as bootup ROM, worth a laugh.

here is the link to Micron's web site describing PCM http://www.micron.com/products/phase-change-memory

Thanks for the link. Only 90 nm 128 Mb available. Any 45 nm Gb must be sampling.

The description of what Nokia is getting from Micron is linked on the top-right of the page that inlewski provided: http://www.micron.com/products/multichip-packages/pcm-based-mcp

DRAM backup? Necessary? Why not direct access?

Going from 90 nm to 45 nm endurance went from 1 million cycles to 100 K cycles. Not good.

Mid-Nov 2012, no PCM shipped to Nokia, but Asha 311 released already Aug 2012? From 11-15-2012: "Bader said that Micron will ship tens of millions of units of 1-Gbit PCM in 2012 in 45-nm process in its leading-edge component, which combines a 1-Gbit PCM die with a 512-Mbit SDRAM and provides a LPDDR2 interface."

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
