Abstract
Embodiments disclose a delay locked loop. The delay locked loop including a main delay circuit configured to generate initial clocks by delaying an internal clock, and sub-delay lines configured to generate phase clocks having a phase difference corresponding to a desired initial delay by respectively delaying the internal clock and the initial clocks. The phase difference among the phase clocks may be adjusted according to delay values of the sub-delay lines.
