IBM reports some advances in their racetrack memory program, and they are now able to measure the movement and processing of data as a magnetic pattern on a nanowire (which is 1,000 finer than a human hair).
Racetrack memory uses electron spin to move data on nanowires at hundreds of miles per hour... IBM is not commercializing it yet, but racetrack memory has the potential to be very lower-power and high-density.
IBM has been working towards racetrack memory for quite some time now, but the last we heard of it was in 2005.
