Rochester cube processor

The University of Rochester on Monday announced it has a working three-dimensional computer chip it calls the cube and is running at 1.4GHz. The nicknamed Rochester cube takes the concept of three-dimensional circuits to a new level, as its processing functions are optimized vertically in the same way as a regular chipís are optimized horizontally, unlike previous attempts that simply stacked regular chips atop one another. Developed by Eby Friedman, Distinguished Professor of Electrical and Computer Engineering at Rochester and faculty director of the processor, and engineering student Vasilis Pavlidis, the 3D chip is described as basically a whole circuit board folded up into a small footprint.
