摘要： A semiconductor apparatus includes a duty cycle correction block and a delay locked loop. The duty cycle correction block generates a duty corrected clock by correcting a duty cycle of an internal clock, adjusts a phase of a rising edge of the duty corrected clock when a delay locked loop is reset, and adjusts a phase of a falling edge of the duty corrected clock when the delay locked loop is locked. The delay locked loop receives an external clock to output the internal clock, and delays the external clock by a variable delay amount to output the internal clock when the adjustment of the phase of the rising edge of the duty corrected clock by the duty cycle correction block is completed.
