ABSTRACT:
A delay locked loop may include a period locked loop portion. The period locked loop portion may include a delay. The delay may include an even number of delay cells dependently connected in the form of a ring configured to generate an even number of delay clock signals. Transition of at least one delay clock signal of the even number of delay clock signals is configured to be controlled in response to an activated one first selecting signal of an even number of first selecting signals, and transition of the remaining clock signals is configured to occur in response to the at least one delay clock signal.
