Abstract:
The present invention provides a magnetic memory device capable of providing high-speed access without increasing an array area. Gate word lines are respectively linearly disposed between source impurity regions and drain impurity regions within a memory cell array area. Gate word line protrusions are respectively provided at boundary regions of memory cell forming regions. Contacts relative to the gate word line protrusions are respectively provided at boundary regions of memory cells at adjacent columns. The drain impurity regions are respectively disposed with being shifted from the centers of the memory cell forming regions in such a manner that spaces between the drain impurity regions become large in the regions in which the protrusions are disposed.
