ABSTRACT:
A sense amplifier control unit include: a control unit that detects a variation in the level of an external voltage and outputs a delay time selection signal on the basis of the result of the detection. A variable delay unit delays an active signal by a delay time corresponding to the delay time selection signal and outputs the delayed signal. A driving signal generating unit outputs a driving signal according to the output of the variable delay unit. A sense amplifier driver drives a sense amplifier on the basis of the driving signal.
