CIRCUIT FOR ADJUSTING CLOCK PHASE AND SEMICONDUCTOR DEVICE INCLUDING THE SAME

摘要

A semiconductor device includes: a buffer configured to receive an input signal; a clock buffer configured to receive a clock; a delay locked loop configured to delay the clock to compensate a path difference between the input signal and the clock; a code generator configured to generate a digital code corresponding to 1/N times the clock period (N is an integer greater than or equal to 2); a delay unit configured to delay the clock compensated by the delay locked loop by a value corresponding to the digital code; and a strobing unit configured to strobe the input signal using the clock delayed by the delay unit.
