ABSTRACT:
In an example, a determination circuit5determines whether an input waveform is a first waveform (=0) or a second waveform (=1). When magnetization switching is caused during writing, the second waveform (=1) having a large voltage change is outputted, and thus the determination circuit5determines that the output waveform is the second waveform, using threshold determination or the like. In another example, when an initial voltage V1agrees with a voltage V2stored by intentionally writing “0”, “0” is outputted; when V1disagrees with V2, “1” is outputted. In the disagreement case, the written data is rewritten into the original data “1.”
