ABSTRACT:
A semiconductor memory device includes a plurality of word lines arranged above a semiconductor substrate to extend in a row direction; a plurality of digit lines arranged above the semiconductor substrate to extend in a column direction orthogonal to the row direction; a power supply line arranged in parallel to the plurality of digit lines; a plurality of memory cells formed on the semiconductor substrate at intersections of the plurality of word lines and the plurality of digit lines, each of the plurality of memory cells having a drain region and a source region; and a linear conductive section arranged under the power supply line. The power supply line is connected with the linear conductive section which is connected with the source regions of the plurality of memory cells. The drain regions of each of columns of the plurality of memory cells are connected with one of the plurality of digit lines, and the plurality of word lines function as gates of the plurality of memory cells.
