Abstract:
1. A magnetic memory device comprising: memory elements based on tunnel magnetoresistance effect elements, each consisting of a magnetization pinned layer in which the direction of magnetization is pinned, a tunnel barrier layer, and a magnetic layer in which the direction of magnetization is variable, which are laid one over another; a first conducting layer formed on one side of the memory element with an insulating layer interposed therebetween; and a second conducting layer formed on the other side of the memory element, wherein information is written into the memory element by applying current to a first conducting layer and also to a second conducting layer, and written information is read out of the memory element through a reading wiring of the memory element which is attached to the connecting hole formed in the insulating layer, the reading wiring being connected to a lower wiring existing below the first conducting layer without passage through the conducting layer in the same level as the first conducting layer.
