Abstract:
1. A magnetic random access memory comprising: a first bit line extending in a first direction; a second bit line which is adjacent to the first bit line in a second direction different from the first direction and which extends in the first direction; a first magnetoresistive effect element which is connected to the first bit line and which has a first fixed layer with a fixed magnetization direction, a first recording layer with an invertible magnetization direction, and a first nonmagnetic layer provided between the first fixed layer and the first recording layer, the magnetization directions of the first fixed layer and the first recording layer being parallel or antiparallel depending on the direction of a first current passed across the first fixed layer and the first recording layer; and a second magnetoresistive effect element which is adjacent to the first magnetoresistive effect element in the second direction and which is connected to the second bit line and which has a second fixed layer with a fixed magnetization direction, a second recording layer with an invertible magnetization direction, and a second nonmagnetic layer provided between the second fixed layer and the second recording layer, the first and second recording layers being formed by a same first layer extending in the second direction, the magnetization directions of the second fixed layer and the second recording layer being parallel or antiparallel depending on the direction of a second current passed across the second fixed layer and the second recording layer.
