Abstract
A semiconductor memory device has pairs of complementary bit lines connected to pairs of complementary data bus lines via transfer elements controlled by column lines. The bit lines are arranged so that mutually adjacent pairs of bit lines are connected to the same pair of data bus lines at a pair of common nodes. The transfer elements for each such mutually adjacent pair of bit lines are controlled by different column lines.
