ABSTRACT:
A semiconductor memory device having a delay locked loop includes a delay locked loop and a voltage supply unit. The delay locked loop reduces the skew between a clock and data. The voltage supply unit supplies the voltages required by the delay locked loop when the delay locked loop is operating and is deactivated when the delay locked loop is not operating.
