Claim 15:
16. A method, comprising:
performing a write operation on a device, where performing the write operation comprises:
heating the device, where the device comprises an electrolyte layer positioned between a reservoir layer and a channel layer that has a variable conductance to a temperature above a state transition temperature, wherein above the state transition temperature the electrolyte layer undergoes a structural state change; and
applying a write voltage between the reservoir layer and the channel layer while the device is above the state transition temperature, wherein responsive to the write voltage being applied, ions or vacancies migrate between the reservoir layer and the channel layer by way of the electrolyte layer, and wherein the conductance of the channel layer changes responsive to the ions or vacancies migrating between the reservoir layer and the channel layer; and

performing a read operation on the device, where performing the read operation comprises:
applying a read voltage between a source and a drain of the device when the device is below the state transition temperature to obtain a value of the conductance of the channel layer, where the source and the drain are coupled to the channel layer, and further where the conductance of the channel layer is substantially invariant when the device is below the state transition temperature and a read voltage is applied between the source and the drain.
