A write control method for a magnetoresistive random access memory, which
includes a memory cell having a recording layer with an axis of easy
magnetization and an axis of hard magnetization. The write control method
includes writing a datum into the memory cell. The writing of the datum
includes applying a pulsative first magnetic field substantially parallel
to the axis of easy magnetization of the recording layer and a pulsative
second magnetic field substantially parallel to the axis of hard
magnetization to the recording layer so as to cause a period of the
pulsative first magnetic field and a period of the pulsative second
magnetic field to overlap each other, and applying a pulsative third
magnetic field having substantially the same direction as the pulsative
first magnetic field to the recording layer at least once after applying
the pulsative first magnetic field to the recording layer.
