The active areas are arranged in the first direction and constitute a plurality of active area columns. Two active area columns adjacent in a second direction are arranged to be half-pitch staggered in the first direction. As viewed from above surfaces of the active areas, each MTJ element is arranged to overlap with one end of each of the active areas. The first and second wirings extend while being folded back in a direction inclined with respect to the first and second directions in order to overlap with the MTJ elements alternately in the adjacent active area columns. | 2012-11-08 |
20120281462 | STORAGE ELEMENT AND STORAGE DEVICE - A storage element includes a storage layer that stores information on the basis of a magnetization state of a magnetic material; a fixed magnetization layer that has a magnetization serving as a reference of the information stored in the storage layer; an interlayer that is formed of a nonmagnetic material and interposed between the storage layer and the fixed magnetization layer; a cap layer that is provided to be adjacent to the storage layer and opposite to the interlayer; and a metal cap layer that is provided to be adjacent to the cap layer and opposite to the storage layer. | 2012-11-08 |
