SEMICONDUCTOR MEMORY DEVICE WITH POWER SUPPLY WIRING ON THE MOST UPPER LAYER

摘要

A memory cell array in a semiconductor substrate has a plurality of memory cells arranged in rows and columns. A first circuit is located at one end of the memory cell array in a column direction. A second circuit is located at the other end of the memory cell array in the column direction. A first wire is located above the memory cell array between the first circuit and the second circuit. The first wire is located in a most upper layer in the semiconductor substrate to supply power to the second circuit.
