ABSTRACT:
An integrated circuit includes a memory element and a circuit. The circuit is configured to program the memory element by applying one or more pulses to the memory element until a sensed resistance of the memory element is within a range of a desired resistance. The one or more pulses have a parameter value that is modified for each subsequent pulse based on the parameter value for an immediately preceding pulse and on a difference between the sensed resistance of the memory element and the desired resistance.
