Abstract
A delay control device and method are disclosed, which relate to a technology for compensating for a delay difference of a delay locked loop (DLL). The delay control device may include a delay locked loop (DLL) configured to adjust a delay time of a delay line, and compensate for a delay time of a replica delay circuit based on a calibration signal. The delay control device may include a real clock path delay circuit configured to delay an output of the delay locked loop (DLL. The delay control device may include a control signal generator configured to generate the calibration signal in consideration of a difference between the delay time of the replica delay circuit and the delay time of the real clock path delay circuit.
