Abstract
A clock signal processor includes a duty cycle corrector, a switch point calculator, and a multiplexer. The duty cycle corrector generates a second clock signal by modifying a duty cycle of a first clock signal. The switch point calculator activates a switch signal at an end of a latency period in which a read command is provided to a non-volatile memory device and an invalid data is read from the non-volatile memory device. The multiplexer outputs one of the first and second clock signals as a third clock signal based on the switch signal.
