ABSTRACT:
A sense amplifier in a semiconductor memory device includes a detection unit for generating complementary state signals showing a state of a pair of bit lines coupled to a plurality of memory cells in the semiconductor memory device in which word lines are coupled to the memory cells, and a latch circuit for receiving the complementary signals and a reference signal and for inverting states of complementary output signals of the latch means only when one of the complementary state signals decreases and becomes lower than the reference voltage.
