A circuit for generating a control signal of a sense amplifier is provided to adjust enable time of a sense amplifier driving line control signal and a sense amplifier ground line control signal easily, by using a delay period control signal generated according to the cutting of a fuse or a test mode signal. A control signal generation part(1) generates a number of control signals enabled according to the cutting of a fuse or a test mode signal and an inversion signal of the control signal. A decoding part(2) generates a number of delay period control signals by decoding a number of control signals inputted from the control signal generation part and the inversion signal of the control signal. A sense amplifier control signal generation part(3) generates a sense amplifier ground line control signal and a sense amplifier driving line control signal controlling the supply of a sense amplifier driving voltage in response to the delay period control signal, and controls enable time of the sense amplifier driving line control signal and the sense amplifier ground line control signal according to the delay period determined by the assembly of the delay period control signal.
