Computing at the nanoscale
Richard Stanley Williams · 2006
Our research group has recently demonstrated the ability to fabricate electronic devices with sub-viral length scales (e.g. -15 nm) and to build nanoscale devices with the capability to perform signal restoration and inversion (required for universal computing) without the need for transistors or any semiconductor at all. This has led us to discover an entirely new logic family based on the Boolean "implication" operation that is specifically suited to the properties of nanoscale switches and crossbars. We have built and demonstrated memory and logic circuits based on these new ideas that exceed the density of today's semiconductor circuits by one to two orders of magnitude.
