Claim Text:
1. A device comprising: a resistive switching device comprising a first electrode, a second electrode, and a resistive switching medium disposed between the first electrode and the second electrode, wherein metal particles from the first electrode are disposed within the resistive switching medium, and wherein the resistive switching device is characterized by at least a first resistive state or a second resistive state; and a first circuit coupled to the first electrode, wherein the first circuit is configured to initiate application of a first state voltage to the first electrode, wherein the first circuit is further configured to monitor a first current flowing through the resistive switching device in response to the first state voltage, and wherein the first circuit is further configured to measure current flowing through the resistive switching device and determine a value of a first current change rate with respect to time at the resistive switching device, and further wherein the first circuit is further configured to terminate the application of the first state voltage to the resistive switching device in response to a determination that the value of the first current change rate satisfies a specified relation with respect to a first threshold current change rate.
