Abstract:
1. A data write method of a magnetic random access memory including a magnetoresistive element which has an axis of easy magnetization and an axis of hard magnetization, a first write wiring which runs in a direction of the axis of easy magnetization, and a second write wiring which runs in a direction of the axis of hard magnetization, comprising: a first phase of supplying a first current to the first write wiring in a first direction and supplying a second current to the second write wiring in a second direction; a second phase of stopping supplying the first current to the first write wiring and supplying the second current to the second write wiring in the second direction; and a third phase of supplying the first current to the first write wiring in a third direction reverse to the first direction and supplying the second current to the second write wiring in the second direction.
