US 7782652 B2Abstract
Nanotube-based switching elements with multiple controls and circuits made from such. A switching element includes an input node, an output node, and a nanotube channel element having at least one electrically conductive nanotube. A control structure is disposed in relation to the nanotube channel element to controllably form and unform an electrically conductive channel between said input node and said output node. The output node is constructed and arranged so that channel formation is substantially unaffected by the electrical state of the output node. The control structure includes a control electrode and a release electrode, disposed on opposite sides of the nanotube channel element. The control and release may be used to form a differential input, or if the device is constructed appropriately to operate the circuit in a non-volatile manner. The switching elements may be arranged into logic circuits and latches having differential inputs and/or non-volatile behavior.

FIG. 6B depicts a state device 660 used as a non-volatile nanotube latch 650 according to another embodiment of the invention. In this embodiment, the control electrodes of the upper inverter 510B, and the release electrodes of the lower inverter 511B, are connected to a logical input signal AT (applied to IN1) via select transistor 662 gated via clock signal CLK and connected to state device 660 at node 671. The control electrodes of the lower inverter, and the release electrodes of the upper inverter, are connected to a complementary version input signal AC (applied to IN2) via select transistor 664 gated via clock signal CLK and connected to state device 660 node 672. In this fashion, a state device may be formed into a nanotube latch 650. Inverter 511B is designed to be the dominant inverter (composed of nanotube devices containing more nanotubes), and 510B is designed to be a feedback inverter (composed of nanotube devices containing less nanotubes) that supplies the charge necessary to compensate for discharge of a state device node in case of noise, for example, as described in the reference book H. B. Bakoglu, “Circuits, Interconnections, and Packaging for VLSI”, Addison-Wesley Publishing Company, pages 349-351. Inverters 511B, 510B, and pass transistors 662 and 664 are ratioed to make sure that latch 660 will switch to the desired state when data is being written to it. Feedback inverter 510B has to be sufficiently weak so that circuits (not shown) that drive state device 660 through clocked devices 662 and 664 can overpower feedback inverter 510B and overcome the latch 650 state stored in state device 660 in the Bakoglu reference. Complementary logic latch outputs are labeled OUT1 and OUT2. Latch 650 is non-volatile; that is, the logic state is preserved if power is turned-off (or disturbed) and resumes operation in the same logic state as the logic state just prior to power turn-off (or interruption).
