Abstract
In a region of a transfer gate provided in a central portion of multilevel writing bit lines, noise in adjacent bit lines at the time of re-writing is counteracted by reversing the order of complementary bit line pair every other pair. With this, in a multilevel dynamic type semiconductor memory device in which one sense amplifier commonly includes a plurality of bit lines and some of the bit lines are selectively activated in a time-dividing manner, the influence of noise between the adjacent bit lines can be deleted.
