PROBLEM TO BE SOLVED: To detect completion of writing data to a resistance change type storage element comprising a conductive electrode at one end of a storage element causing a resistance change and a readout electrode at the other end thereof to cause the resistance change in the storage element by applying a current to the conductive electrode.SOLUTION: A data writing device 1 of a resistance change type storage element, which has a conductive electrode at one end of a storage element causing a resistance change and a readout electrode at the other end thereof to cause a resistance change in the storage element by applying a writing current to the conductive electrode, comprises writing means, output means, and control means. The output means is provided between a power supply and the readout electrode, and a readout signal from the storage element and a monitor signal for monitoring a writing state of the storage element by the writing means are output from the output means as output signals. The completion of writing data to the resistance change type storage element is detected by the monitor signal.SELECTED DRAWING: Figure 1
