In even more "future tech" news, Micron announced today that it has started mass production of a 45nm phase change memory solution for mobile devices. Phase change memory -- so called because it uses heat from an electrical current to flip between varying physical states -- is considered a possible successor, or at least competitor, to Flash in the non-volatile memory market. Micron's chip is the first phase change memory solution to become widely available in quantity.
Engineers at IBM Research in Zurich, Switzerland claim they've come up with a breakthrough in phase change memory (PCM) technology that, for the first time, would allow it to store data for longer periods, potentially paving the way for lower cost solid state chips that are faster and more reliable than today's multi-level cell (MLC) flash memory chips. The trick is in figuring out a solution to a problem called "drift."
