  • Publication number: 20070235708
    Abstract: A programmable link structure for use in three dimensional integration (3DI) semiconductor devices includes a via filled at least in part with a phase change material (PCM) and a heating device proximate the PCM. The heating device is configured to switch the conductivity of a transformable portion of the PCM between a lower resistance crystalline state and a higher resistance amorphous state. Thereby, the via defines a programmable link between an input connection located at one end thereof and an output connection located at another end thereof.

  • Publication number: 20070235784
    Abstract: A switching circuit configured for controlling static power consumption in integrated circuits includes a plurality of three-terminal, phase change material (PCM) switching devices connected between a voltage supply terminal and a corresponding sub-block of integrated circuit logic. Each of the PCM switching devices further includes a PCM disposed in contact between a first terminal and a second terminal, a heating device disposed in contact between the second terminal and a third terminal, the heating device positioned proximate the PCM, and configured to switch the conductivity of a transformable portion of the PCM between a lower resistance crystalline state and a higher resistance amorphous state; and an insulating layer configured to electrically isolate the heater from said PCM material, and the heater from the first terminal.

  • Publication number: 20070145347
    Abstract: The present invention relates to a device structure that contains two or more conducting layers, two peripheral insulating layers, one or more intermediate insulating layers, and two or more conductive contacts. The two or more conducting layers are sandwiched between the two peripheral insulating layers, and they are spaced apart by the intermediate insulating layers to form two or more quantum wells. Each of the conductive contacts is directly and selectively connected with one of the conducting layers, so the individual quantum wells can be selectively accessed through the conductive contacts. Such a device structure preferably contains a coupled quantum well devices having two or more quantum wells that can be coupled together by inter-well tunneling effect at degenerate energy levels. More preferably, the device structure contains a memory cell having three quantum wells that can be arranged and constructed to define two different memory states.

  • Publication number: 20050045872
    Abstract: A qubit (quantum bit) circuit includes a superconducting main loop that is electrically-completed by a serially-interconnected superconducting subloop. The subloop includes two Josephson junctions. A first coil provides a first flux that couples with the main loop but not with the subloop. A second coil provides a second flux that couples with the subloop but not with the main loop.
