Micron ships phase-change memory

LONDON – Memory chip vendor Micron Technology Inc. has backfilled its range of 45-nm phase-change memory (PCM), which it says is shipping in "high volume" to Nokia, as reported by EE Times in November.
Micron (Boise, Idaho) has announced it has been shipping 45-nm 1-Gbit PCM multchip package to Nokia for use in the their phones for some time and is now sampling a 512-Mbit PCM plus 512-Mbit LPDDR2 MCP. Nokia is using Micron's PCM solution to enrich the functionality of "select devices" in its portfolio, Micron said.
At the time of the Electronica exhibition EE Times referenced a Micron executive saying that Micron will ship tens of millions of units of 1-Gbit PCM in 2012. Micron's volume comes from a couple of cell phone design wins (see Micron phase-change memory to skip a node). One is the Nokia Asha phone (see www.nokia.com/global/products/asha).
"Nokia has always found ways to provide innovative mobile devices for its customers across the globe, and Micron's PCM for mobile enables us to enhance the performance of Asha smartphones," said Dirk Didascalou, senior vice president for mobile phones at Nokia, in a statement issued by Micron. "Micron is a trusted supplier, and their new technology helps create a strong user experience with a number of feature and performance enhancements."
Micron said its PCM can speed up boot time for mobile phones at switch-on, simplify software development and boost performance with its overwrite capability. Micron's 45-nm PCM components are being targeted at mobile phones with a future devices aimed at smartphones and tablet computers, the company said.
Micron's 45nm PCM solution is currently targeted for utilization in mobile phones bringing enhanced capabilities, with a future roadmap aimed at addressing smartphones and media tablets.

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 :)

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

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

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."
