Magnetic random access memory |
摘要 |
A magnetic field H 1 in the hard-axis direction and a magnetic field H 2 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 (H 1 )}+{right arrow over (H 2 )}+{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.
