    • A device provides an electrically settable resistance and comprises first and second electrodes. Each electrode comprises a redox active material. The device further comprises means defining an environment for each electrode such that the average redox state of the electrodes, taken together, remains substantially constant. The environment-defining means includes an electrolyte between the electrodes. The device further comprises a pair of terminals electrically connected to the first electrode at spaced-apart locations, the electrically settable resistance being defined between the pair of terminals and being a function of the oxidation state of the first electrode. The device further comprises means, including a terminal electrically connected to the second electrode, for defining a control circuit path, including the first and second electrodes and the electrolyte, to enable a control current flowing through the control circuit path to change the oxidation state of the first electrode so that control current flowing in one direction sets the resistance to a lower value and control current flowing in the opposite direction sets the resistance to a higher value.
    • 一种器件提供电可设置电阻并且包括第一和第二电极。 每个电极包含氧化还原活性材料。 该装置还包括限定每个电极的环境的装置,使得电极的平均氧化还原状态一起保持基本上恒定。 环境限定装置包括电极之间的电解质。 该装置还包括在间隔开的位置电连接到第一电极的一对端子,电可设定电阻限定在该对端子之间,并且是第一电极的氧化状态的函数。 该装置还包括装置,其包括电连接到第二电极的端子,用于限定包括第一和第二电极和电解质的控制电路路径,以使得流过控制电路路径的控制电流能够改变氧化态 第一电极使得在一个方向上流动的控制电流将电阻设置为较低的值,并且以相反方向流动的控制电流将电阻设置为较高的值。
