Graphene Chip Reaches the Level of a 1979 Zilog Z8000 | NextBigFuture.com

Max Shulaker and a group of researchers he leads has developed a working 16-bit microprocessor built from over 14,000 carbon nanotube transistors that is the most complex ever demonstrated. The techniques they have come up with can be implemented with equipment used for making conventional silicon chips, which means chipmakers won’t have to invest in expensive new gear if they want to make nanotube processors. They got around the intermixing problem. They discovered that some kinds of logic gates, which are fundamental building blocks of digital circuits, were more resistant to problems triggered by metallic-like nanotubes than others. That led
