Another circulating memory scheme. We've had acoustical delay lines, drums, magnetic bubbles, CCDs, ... Racetrack memory works by storing data as magnetic regions (also called domains), which would be transported along nanowire "racetracks." Instead of forcing a computer to seek out the data it needs, as traditional computing systems do, the information would automatically slide along the racetrack to where it could be used. The result: powerful and efficient computing. And they tout the potential latency as an advantage in the form of some sort of simplicity. Well, it might work, and I might eat crow. -- gil Gil: Since you brought up "acoustical". This is semi off topic but interesting to (me). I am having heart issues and the hospital gave me a little monitoring device that listens for irregularities in your heart rhythm and then records in inside a box (which I think is memory but not sure) anyway after so many "hits" you are supposed to disconnect it and then dial a phone number which is essentially a PC but the interesting part of this is the box that they give you is essentially an acoustic coupler which you place on a level surface and then the phones receiver is placed on top on the small box and then you press a button and you can hear the modems sync up and then it transmits to the PC all the recording that the little box has in it and then when its done it hangs up. So 1960's technology still is out there!
