ABSTRACT:
A semiconductor memory includes a memory cell array area having a memory cell, a word line contact area adjacent to the memory cell array area, a word line arranged straddling the memory cell array area and the word line contact area, a contact hole provided on the word line in the word line contact area, and a word line driver connected to the word line via the contact hole. A size of the contact hole is larger than a width of the word line, and the lowest parts of the contact hole exist on a position lower than a top surface of the word line and higher than a bottom surface of the word line.
