    • Multi-functional electronic switching and current control device comprising a chalcogenide material. The devices include a load terminal, a reference terminal and a control terminal. Application of a control signal to the control terminal permits the device to function in one or more of the following modes reversibly: (1) a gain mode in which gain is induced in the current passing between the load and reference terminals; (2) a conductivity modulation mode in which the conductivity of the chalcogenide material between the load and reference terminals is modulated; (3) a current modulation mode in which the current or current density between the load and reference terminals is modulated; and/or (4) a threshold modulation mode in which the voltage required to switch the chalcogenide material between the load and reference terminals from a resistive state to a conductive state is modulated. The devices may be used as interconnection devices or signal providing devices in circuits and networks.

    • A multi-terminal logic device. The device includes a phase change material having crystalline and amorphous states in electrical communication with three or more electrical terminals. The phase change material is able to undergo reversible transformations between amorphous and crystalline states in response to applied electrical energy where the amorphous and crystalline states show measurably distinct electrical resistances. Electrical energy in the form of current or voltage pulses applied between a pair of terminals influences the structural state and measured electrical resistance between the terminals. In the instant devices, independent input signals are provided between different pairs of terminals and the output is measured as the resistance between yet another pair of terminals. Logic functionality is achieved through relationships between the applied input signals and the measured output resistance where the relationship is governed by the effect of the input signals on the structural state and electrical resistance of the phase change material. Logic values may be associated with the crystalline and amorphous states of the phase change material or the measured resistance between a pair of terminals.
    • 多终端逻辑器件。 该装置包括具有与三个或更多个电端子电连通的晶体和无定形状态的相变材料。 相变材料能够响应于所施加的电能在无定形和结晶状态之间经历可逆变换,其中非晶态和结晶态显示出可测量的不同电阻。 施加在一对端子之间的电流或电压脉冲形式的电能影响端子之间的结构状态和测量的电阻。 在即时设备中,在不同的终端对之间提供独立的输入信号,并且输出被测量为另一对终端之间的电阻。 逻辑功能通过所施加的输入信号与测量的输出电阻之间的关系实现,其中该关系由输入信号对相变材料的结构状态和电阻的影响所决定。 逻辑值可能与相变材料的晶态和非晶状态或一对端子之间测得的电阻相关。
