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.
