Scientists from the University of Cambridge have created, for the first time, a new type of microchip which allows information to travel in three dimensions. Currently, microchips can only pass digital information in a very limited way - from either left to right or front to back. The research was published today, 31 January, in Nature.
Dr Reinoud Lavrijsen, an author on the paper from the University of Cambridge, said: “Today’s chips are like bungalows - everything happens on the same floor. We’ve created the stairways allowing information to pass between floors.”
Researchers believe that in the future a 3D microchip would enable additional storage capacity on chips by allowing information to be spread across several layers instead of being compacted into one layer, as is currently the case.
