A read blocks (BKjn) are connected to a read bit line (BLj). The read block (BKjn) has MTJ elements (12) connected in series or in parallel, or arranged by combining series and parallel connections between the read bit line (BLj) and a ground terminal (VSS). The MTJ elements (12) are stacked on a semiconductor substrate. The read bit line (BLj) is arranged on the MTJ elements (12) stacked. A write word line (WWL3n, WWL3n+1, WWL3n+2) extending in the X-direction and a write bit line (BLj0, BLj1) extending in the Y-direction are present near the MTJ elements (12) in the read block (BKjn). <IMAGE> |
