Abstract:
A semiconductor memory device comprises a plurality of first row lines arranged in parallel; a plurality of column lines intersecting the first row lines; a plurality of storage elements arranged at intersections of the first row lines and the column lines; a plurality of second row lines arranged in parallel with the first row lines, from positions opposite to the first row lines via the column lines to a certain portion of the column line, and capacitively coupled with the column lines; and a sense amplifier including a field effect transistor having a lower layer control electrode composed of the certain portion of the column line, and an upper layer control electrode composed of the second row line capacitively coupled in the upper layer with the certain portion of the column line.
