US Patent 7985906 - Nanotube-based logic circuits

http://www.freepatentsonline.com/7985906.html

This patent from Nantero focuses on logic circuit designs based on their carbon nanotube switching fabrics. Claim 1 reads:

1. A Boolean logic circuit, comprising

at least one input terminal and an output terminal; and

a network of nanotube switching elements electrically disposed between said at least one input terminal and said output terminal, each of said nanotube switching elements comprising:

a first terminal;

a second terminal; and

a nanotube channel element;

wherein the nanotube channel element is configured to form a conductive path between the first and second terminals of the nanotube switching element in response to electrical stimulus applied to the nanotube switching element;

said network of nanotube switching elements effectuating a Boolean function transformation of Boolean signals on said at least one input terminal, said Boolean function transformation including a Boolean inversion within the function.
