haunting memories
http://www.nytimes.com/2007/09/11/technology/11storage.html?_r=1&th&emc=th&oref=slogin if an idea that Stuart S. P. Parkin is kicking around in an I.B.M. lab here is on the money, electronic devices could hold 10 to 100 times the data in the same amount of space. That means the iPod that today can hold up to 200 hours.... If he proves successful in his quest, he will create a “universal” computer memory, one that can potentially replace dynamic random access memory, or DRAM, and flash memory chips, and even make a “disk drive on a chip” possible....... His research group is able to slide the tiny magnets along notched nanowires at speeds greater than 100 meters a second. Since the tiny magnetic domains have to travel only submolecular distances, it is possible to read and write magnetic regions with different polarization as quickly as a single nanosecond — far faster than existing storage technologies.......
