Summary:PURPOSE: A sense amplification device for a semiconductor memory device is provided to stabilize an operation of a latch circuit connected with an output terminal of the sense amplification device by reducing an average voltage level of an output signal of the sense amplification device though a supply voltage increases, and to easily adjust a voltage gain. CONSTITUTION: The device includes a sense amplifier(40) amplifying an input signal and an inverting input signal, a complete differential amplifier(42) amplifying an output of the sense amplifier, and a latch(44) latching an output of the complete differential amplifier. The complete differential amplifier includes the first and second differential amplifiers and an output voltage level control circuit. The first differential amplifier(MP9,MP10,MN12,MN13) increases the output of the complete differential amplifier when the input signal is higher than the inverting input signal and decreases the output when vice versa. The second differential amplifier(MP11,MP12,MN14,MN15) decreases the inverting output of the complete differential amplifier when the input signal is higher than the inverting input signal and decreases the output when vice versa. The output voltage level control circuit(60) controls the output signal and the inverting output signal.
