Patent ID: 7138832

Claim:
A Boolean logic circuit, comprising: at least one input terminal and an output terminal; a network of nanotube switching elements electrically disposed between said at least one input terminal and said output terminal; said network of nanotube switching elements effectuating a Boolean NOT function transformation of Boolean signals on said at least one input terminal, said Boolean function transformation including a Boolean inversion within the function; wherein said network of nanotube switching elements includes a first and a second nanotube switching element, each nanotube switching element including: an output node; a nanotube channel element having at least one electrically conductive nanotube; and a control electrode disposed in relation to the nanotube channel element to controllably form an electrically conductive channel to the output node; wherein the at least one input terminal of the Boolean logic circuit is in electrical communication with the control electrodes of the first and second nanotube switching elements; wherein the output nodes of the first and second nanotube switching elements are electrically coupled together and to the output terminal of the Boolean logic circuit; wherein the nanotube channel element of the first nanotube switching element is in electrical communication with a logical true value, and the nanotube channel element of the second nanotube switching element is in electrical communication with a logical false value.
