Abstract
A semiconductor integrated circuit is provided in which a differential amplifier circuit such as a sense amplifier is operated at high speed even if the operating voltage is reduced. To achieve this, a MOS transistor for supplying the operating voltage to a drive line on the high-potential side of a differential amplifier circuit is of N-channel type and the amplitude of a switching control signal for controlling this transistor is the potential of the step-up voltage produced by stepping up a supply voltage in level. The output voltage of an internal step-up circuit for achieving a word-line selection level is utilizable as the step-up voltage.
