ABSTRACT:
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.
