    摘要: The present invention is directed to structures and methods of fabricating electromechanical memory cells having nanotube crossbar elements. Such memory cells include a substrate having transistor with a contact that electrically contacts with the transistor. A first support layer is formed over the substrate with an opening that defines a lower chamber above the electrical contact. A nanotube crossbar element is arranged to span the lower chamber. A second support layer is formed with an opening that defines a top chamber above the lower chamber, the top chamber including an extension region that extends beyond an edge of the lower chamber to expose a portion of the top surface of the first support layer. A roof layer covers the top of the top chamber and includes an aperture that exposes a portion of the extension region of the top chamber and includes a plug that extends into the aperture in the roof layer to seal the top and bottom chambers. The memory cell further includes an electrode that overlies the crossbar element such that electrical signals can activate the electrode to attract or repel the crossbar element to set a memory state for the transistor.

The Boolean logic circuits include input and output terminals and a network of nanotube switching elements electrically disposed between said at least one input terminal and said output terminal. Each 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 along the nanotube channel element. At least one nanotube switching element non-volatilely retains an informational state and at least one nanotube switching elements volatilely retains an informational state. The network of nanotube switching elements effectuates a Boolean function transformation of Boolean signals on said at least one input terminal. Dual rail cascode logic circuits may also be constructed from the nanotube switching elements.

The storage cell is an electro-mechanical data retention cell in which the physical positional state of a storage cell element represents the informational state of the cell. The storage cell element is a carbon nanotube switching element. The storage is writable with supply voltages used by said cell selection circuitry. The storage is writable and readable via said selection circuitry with write times and read times being within an order of magnitude. The write times and read times are substantially the same. The storage has no charge storage or no charge trapping.

    摘要: Non-volatile field effect devices and circuits using same. A non-volatile field effect device includes a source, drain and gate with a field-modulatable channel between the source and drain. Each of the source, drain, and gate have a corresponding terminal. An electromechanically-deflectable, nanotube switching element is electrically positioned between one of the source, drain and gate and its corresponding terminal. The others of the source, drain and gate are directly connected to their corresponding terminals. The nanotube switching element is electromechanically-deflectable in response to electrical stimulation at two control terminals to create one of a non-volatile open and non-volatile closed electrical communication state between the one of the source, drain and gate and its corresponding terminal.
