    摘要: Field effect devices having a gate controlled via a nanotube switching element. Under one embodiment, 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 gate structure is disposed over an insulator over the channel region and has a corresponding terminal. A nanotube switching element is responsive to a first control terminal and a second control terminal and is electrically positioned in series between the gate structure and the terminal corresponding to the gate structure. The nanotube switching element is electromechanically operable to one of an open and closed state to thereby open or close an electrical communication path between the gate structure and its corresponding terminal. When the nanotube switching element is in the closed state, the channel conductivity and operation of the device is responsive to electrical stimulus at the terminals corresponding to the source and drain regions and the gate structure.

    摘要: Random access memory including nanotube switching elements. A memory cell includes first and second nanotube switching elements and an electronic memory. Each nanotube switching element includes conductive terminals, a nanotube article and control circuitry capable of controllably form and unform an electrically conductive channel between the conductive terminals. The electronic memory is a volatile storage device capable of storing a logic state in response to electrical stimulus. In certain embodiment the electronic memory has cross-coupled first and second inverters in electrical communication with the first and second nanotube switching elements. The cell can operate as a normal electronic memory, or can operate in a shadow memory or store mode (e.g., when power is interrupted) to transfer the electronic memory state to the nanotube switching elements. The device may later be operated in a recall mode where the state of the nanotube switching elements may be transferred to the electronic memory.
