Abstract:
A delay locked-loop circuit includes: a phase comparator detecting a phase difference between an external clock and an internal clock; an up/down counter controlling a delay time in accordance with an output signal from the phase comparator; and a delay line including plural unit delay circuits corresponding to plural bits of a signal output from the up/down counter in order to control the delay of the external clock to conform the external clock to the internal clock, and in which the unit delay circuits controlled by the output from a same bit in the output from the up/down counter are not connected adjacently to each other in the connection of the plural unit delay circuits in series.
