Micron first to market with phase-change memory modules for portable devices (video)
Look out silicon and magnetic storage, here comes glass. Micron has announced production of the first commercial cellphone phase-change memory (PCM) modules, a type of flash RAM that works by changing a crystal solid to an amorphous state. The 1Gb chips will share a circuit board with 512Mb of standard volatile memory, just enough to go in feature phones for now — but the company claims it will eventually offer larger modules for smartphone and tablet storage as well. PCM could scale to much faster speeds than conventional NAND flash, since it doesn’t require a time-sapping erase before rewriting — and with read speeds of 400MB/s, it’s already into regular flash territory while still just a first generation product
