MEMORY MAKER Micron has announced high volume availability of its 45nm phase change memory (PCM) chips.

Micron has been pushing the development of PCM chips with Intel for a number of years and is finally at a stage where it can offer chips to its customers. The firm announced that its 45nm PCM chips are available in a 1Gb PCM plus a 512Mb LPDDR2 package for mobile devices.

Micron claims its PCM memory can improve boot time, low power consumption and high reliability. The firm said the interface between the LPDDR2 and the PCM is complaint with JEDEC standards.

Phase change memory uses the state change of chalcogenide glass when a current is passed through it. Micron isn't the first company to look into phase change memory, with Samsung and ST Microelectronics announcing prototypes in years gone by, however Micron is the first company to put it into volume production.

Tom Eby, VP of Micron's Wireless Solutions Group said, "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."

While Micron's latest memory technology promises a lot, the firm is pitching it at feature phones, with modules for smartphones and tablets expected in the future. µ
