摘要： A magnetic field H1 in the hard-axis direction and a magnetic field H2 in the easy-axis direction are caused to simultaneously act on a MTJ element having an ideal asteroid curve, thereby reversing the magnetizing direction of the storing layer of the MTJ element. When the actual asteroid curve shifts in the hard-axis direction by Ho, a corrected synthesized magnetic field ({right arrow over (H1)}+{right arrow over (H2)}+{right arrow over (Ho)}) is generated in write operation to reliably reverse the magnetizing direction. The corrected synthesized magnetic field can easily be generated by individually controlling a write word/bit line current on the basis of programmed setting data.

摘要： A write word line is disposed right under a MTJ element. The write word line extends in an X direction, and side and lower surfaces of the write word line are coated with a hard magnetic material and yoke material. The hard magnetic material is magnetized by a surplus current passed through the write word line, and a characteristic of the MTJ element is corrected by residual magnetization. A data selection line (read/write bit line) is disposed right on the MTJ element. The data selection line extends in a Y direction intersecting with the X direction, and a part of the surface of the data selection line is coated with the yoke material.
