摘要： Phase change devices, and particularly multi-terminal phase change devices, include first and second active terminals bridged together by a phase-change material whose conductivity can be modified in accordance with a control signal applied to a control electrode. This structure allows an application in which an electrical connection can be created between the two active terminals, with the control of the connection being effected using a separate terminal or terminals. Accordingly, the resistance of the heater element can be increased independently from the resistance of the path between the two active terminals. This allows the use of smaller heater elements thus requiring less current to create the same amount of Joule heating per unit area. The resistance of the heating element does not impact the total resistance of the phase change device. The programming control can be placed outside of the main signal path through the phase change device, reducing the impact of the associated capacitance and resistance of the device.

摘要： Methods and apparatus for programming a phase change device (PCD) to a low resistance state. According to an exemplary method, one or more first programming pulses having a predetermined magnitude and/or duration are applied to a PCD. After each programming pulse is applied, the programmed resistance of the PCD is compared to a target resistance specification. If the programmed resistance is not in accordance with the target resistance specification, one or more second programming pulses having a magnitude and/or duration different than the magnitude and/or duration of the one or more first programming pulses are applied to the PCD. This process is repeated until the programmed resistance of the PCD satisfies the target resistance specification or it is determined that the PCD cannot be programmed to a resistance value that satisfies the target resistance specification.

摘要： Impedance matching and trimming apparatuses and methods using programmable resistance devices. According to one exemplary embodiment, the impedance matching circuit includes a programmable resistance element, a comparator, a resistor divider having a common node coupled to a first input of the comparator, and an impedance element control circuit coupled between an output of the comparator and the programmable resistance element. The programmable resistance element includes one or more programmable resistance devices (PRDs). Programmed resistances of the programmable resistance element combine with the resistance of an external reference resistor to provide an impedance matched termination. A change in the resistance of the termination impedance causes a change in the output of the comparator. The impedance element control circuit responds to changes in the output of the comparator by providing one or more program control output signals, which control the resistance values of one or more of the PRDs, thereby maintaining an impedance matched termination.
