A signal generator produces enable signals for bitline sense amplifiers in a semiconductor device. The signal generator includes a first driving element for producing a first enable signal at a first output line in response to first and second control signals, a second driving element for producing a second enable signal at a second output line in response to inverted signals of the first and second control signals, and an equalizing element connected between the first output line and the second output line for equalizing the first and second output lines in response to a third control signal. A control signal generating element generates the first, second, and third control signals, and inverted signals thereof, in response to predetermined input signals. The DC current generated from an output driver and the charging and discharging current of output loading can be reduced, to thereby reduce power consumption. Also, when the output signals are applied as enable signals of bitline sense amplifiers, an initial invalid sensing the bitline sense amplifier circuits can be avoided.
