ABSTRACT:
A write drive circuit provided for every write word line supplies a data write current to a write word line of a selected row, and supplies a magnetic-field canceling current to a write word line of an adjacent row in the opposite direction to that of the data write current. In each write drive circuit, the data write current is supplied in response to turning-ON of first and second driver transistors, and the magnetic-field canceling current is supplied in response to turning-ON of the second driver transistor.
