Abstract
A magnetic memory device comprises a memory cell assembled by first and second tunnel junction portions and a switch, each of the first and second tunnel junction portions being formed of a stack of a pinned layer in which a magnetization direction is fixed and a record layer in which a magnetization direction changes depending on an external magnetic field. A first data line is connected to a first end of the first tunnel junction portion. A second data line is connected to the first end of the second tunnel junction portion. A bit line is connected to the second end of the first tunnel junction portion and the second end of the second tunnel junction portion via the switch.
