    摘要: A four terminal non-volatile transistor device. A non-volatile transistor device includes a source region and a drain region of a first semiconductor type of material and each in electrical communication with a respective terminal. A channel region of a second semiconductor type of material is disposed between the source and drain region. A floating gate structure is made of at least one of semiconductive or conductive material and is disposed over the channel region. A control gate is made of at least one of semiconductive or conductive material and is in electrical communication with a respective terminal. An electromechanically-deflectable nanotube switching element is in electrical communication with one of the floating gate structure and the control gate structure, and is positioned to be electromechanically deflectable into contact with the other of the floating gate structure and the control gate structure. When the nanotube switching element is in communication with both the control gate and the floating gate, the control gate may be used to modulate the conductivity of the channel region. The nanotube switching element may be formed from a porous fabric of a monolayer of single-walled carbon nanotubes. Under certain embodiments, the nanotube article is suspended vertically in relation to the horizontal substrate. Under certain embodiments, a release gate and release node are positioned in spaced relation to the nanotube switching element, and, in response to a signal on the release node, the release gate electromechanically deflects the nanotube switching element out of contact with the one of the control gate and floating gate. Under certain embodiments, the contact between the nanotube switching element and the one of the control gate and floating gate is a non-volatile state. Under certain embodiments, the device occupies an area of 8F2.

    摘要: Nanotube-based switching elements and logic circuits. Under one embodiment of the invention, a switching element includes an input node, an output node, a nanotube channel element having at least one electrically conductive nanotube, and a control electrode. The control electrode is disposed in relation to the nanotube channel element to controllably form an electrically conductive channel between the input node and the output node. The channel at least includes said nanotube channel element. The output node is constructed and arranged so that channel formation is substantially unaffected by the electrical state of the output node. Under another embodiment of the invention, the control electrode is arranged in relation to the nanotube channel element to form said conductive channel by causing electromechanical deflection of said nanotube channel element. Under another embodiment of the invention, the output node includes an isolation structure disposed in relation to the nanotube channel element so that channel formation is substantially invariant from the state of the output node. Under another embodiment of the invention, the isolation structure includes electrodes disposed on opposite sides of the nanotube channel element and said electrodes produce substantially the same electric field. Under another embodiment of the invention, a Boolean logic circuit includes 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. The network of nanotube switching elements effectuates a Boolean function transformation of Boolean signals on said at least one input terminal. The Boolean function transformation includes a Boolean inversion within the function, such as a NOT or NOR function.

    摘要: The present disclosure generally relates to multi-switch storage cells (MSSCs), three-dimensional MSSC arrays, and three-dimensional MSSC memory. Multi-switch storage cells include a cell select device, multiple resistive change elements, and an intracell wiring electrically connecting the multiple resistive change elements together and to the cell select device. MSSC arrays are designed (architected) and operated to prevent inter-cell (sneak path) currents between multi-switch storage cells, which prevents stored data disturb from adjacent cells and adjacent cell data pattern sensitivity. Additionally, READ and WRITE operations may be performed on one of the multiple resistive change elements in a multi-switch storage cell without disturbing the stored data in the remaining resistive change elements. However, controlled parasitic currents may flow in the remaining resistive change elements within the cell. Isolating each multi-switch storage cell in a three-dimensional MSSC array, enables in-memory computing for applications such as data processing for machine learning and artificial intelligence.

    摘要: The present disclosure is directed toward carbon based diodes, carbon based resistive change memory elements, resistive change memory having resistive change memory elements and carbon based diodes, methods of making carbon based diodes, methods of making resistive change memory elements having carbon based diodes, and methods of making resistive change memory having resistive change memory elements having carbons based diodes. The carbon based diodes can be any suitable type of diode that can be formed using carbon allotropes, such as semiconducting single wall carbon nanotubes (s-SWCNT), semiconducting Buckminsterfullerenes (such as C60 Buckyballs), or semiconducting graphitic layers (layered graphene). The carbon based diodes can be pn junction diodes, Schottky diodes, other any other type of diode formed using a carbon allotrope. The carbon based diodes can be placed at any level of integration in a three dimensional (3D) electronic device such as integrated with components or wiring layers.
