Racetrack memory chips from Stuart Parkin
December 11th, 2009 | 
Author: Stuart Parkin- a former IBM think tank is now developing a three dimensional memory system which is good enough to replace all two dimensional memory systems. In fact, all memory systems are two dimensional at present, but a three dimensional memory system implemented with the help of nano wires will define next generation memory chips and hard drives.
If you go for a comparison, you would find that this race track memory system has a very huge storage capacity when compared to magnetic tapes and speed is lot higher when compared to flash chips. When comparing the performance of racetrack chips, one would find that it is way ahead or superior to magnetic tapes and flash chips. All is done with the help of a set of nano wires, arranged in U shape adjacent to each other. Electric current is passed through the wires which produce desired effects helpful for reading and writing data.
