Abstract
A control circuit is provided herein, which can suppress the prolongation of a delay operation, so that the sequence using the DLL circuit to adjust the delay of the internal clock signal can be finished within a predetermined execution period. A control circuit includes a delay control unit delaying an input clock signal to generate an output clock signal based on the phase difference between the input clock signal and an output clock signal. The control circuit further includes a clock control unit. When the phase difference is greater than the first predetermined amount, the clock control unit inputs a clock signal delayed from the input clock signal by a second predetermined amount to the delay control unit as the input clock signal.
