Abstract:
A magnetic memory device comprising:a memory cell assembled by first and second tunnel junction portions and a cell selection semiconductor element, each of said first and second tunnel junction portions being formed of a stack of a pinned layer in which a magnetization direction is fixed and a recording layer in which a magnetization direction changes depending on an external magnetic field, said stack having single or multiple tunnel junctions, said first tunnel junction section having a first end and a second end opposed to each other in the stacking direction, said second tunnel junction portion having a third end and a fourth end opposed to each other in the stacking direction; a first data line connected to said first end of said first tunnel junction section; a second data line connected to said third end of said second tunnel junction section; and a bit line connected to said second end of said first tunnel junction portion and said fourth end of said second tunnel junction section via said cell selection semiconductor element.
