Abstract
An apparatus for detecting a lock failure and correcting a duty cycle includes a lock failure detector configured to determine whether a first internal clock signal is locked to a second internal clock signal and to output a lock failure signal in response thereto, a duty cycle correction unit configured to correct a duty cycle of an external clock signal responsive to the lock failure signal and to output the duty-cycle-corrected external clock signal as the first internal clock signal, and a delay unit configured to generate the second internal clock signal by delaying the first internal clock signal.
