Abstract

A semiconductor integrated circuit device is provided which includes a memory cell array located in a generally central area of a semiconductor substrate with peripheral circuits located at both ends of the semiconductor substrate. A wiring layer is also provided which couples the peripheral circuits to one another. This wiring layer is arranged to have a double-layer structure of first and second aluminum layers which are electrically coupled to one another.
