Abstract
A delay locked loop includes a replica delay oscillator unit, a division unit, a pulse generation unit, a code value output unit, and a delay line. The replica delay oscillator unit generates a replica oscillation signal having a period corresponding to a replica delay. The division unit receives the replica oscillation signal and a clock signal and divides the replica oscillation signal and the clock signal at a first or second ratio in response to a delay locking detection signal. The pulse generation unit generates a delay pulse having a pulse width corresponding to a delay amount for causing a delay locking. The code value output unit adjusts a code value corresponding to the pulse width of the delay pulse in response to the delay locking detection signal. The delay line delays the clock signal in response to the code value.
