Abstract
In a line configuration of each memory cell array employed in a semiconductor memory device, a pair of bit line signal input/output lines or a pair of input/output data lines for transmitting complementary signals are disposed on both sides of and adjacent the global word line so as to cancel the influence of the global word line. By these configurations, the number of shielded lines may be reduced and the width of each line and the interval between the lines are arrayed for preventing the respective lines from breaking or being short-circuited.
