摘要: An integrated circuit includes a resistance changing memory element and a circuit. The circuit is configured to program the memory element by iteratively applying a variable program pulse to the memory element until a resistance of the memory element crosses a first reference resistance. The variable program pulse is adjusted for each iteration such that the resistance of the memory element approaches the first reference resistance.
