Saturday, July 21, 2012:
Micron said its first phase change memory (PCM) solution for mobile devices features 1-gigabit (Gb) PCM plus 512-megabit (Mb) LPDDR2 in a multi-chip package. The 1-Gb product is targeted at high-end feature phones, which can benefit from the speed of the read in PCM and simplified software development.

Philippe Berge, senior director of NOR, PCM, e.MMC business for Micron's Wireless Solutions Group said: "This is the first product using 45-nm technology, which is really validating high-volume manufacturing of this disruptive technology. We are now at the stage that we can demonstrate that PCM delivers according to our plans. And that will really be the difference. Based on that, we are going to have some kind of proliferation in both directions to extend our coverage of the high-volume feature phone market and also later on to address the smartphone market."
PCM claims advantages over traditional memory devices in areas such as boot time, simplified software development, performance and overwrite capability. The technology is also said to be power efficient. However, the technology has hit a number of obstacles on the road to deployment. detractors argue that it will never be cost competitive with traditional types of memory, and there are also lingering concerns about PCM's temperature sensitivity.
Micron maintains that its PCM product line has established a foothold in the wireless industry, citing as evidence relationships with global customers and enablers, engagement with device manufactures and cooperation with Intel Mobile Communications, which includes recent PCM qualification.
Tom Eby, VP of Wireless Solutions Group at Micron, added: "Our commitment to innovation and continued development of advanced products to address the voracious demands of the wireless industry is clear and strong. We are determined to evolve and innovate by continuing to offer the best-tailored solutions for both today's and tomorrow's market requirements."
