A data write method of a magnetic random access memory including a
magnetoresistive element which has axis of easy and hard magnetizations,
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, includes 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.
