Semiconductor apparatus and a semiconductor system capable of adjusting timings of data and data strobe signal

Abstract

A semiconductor apparatus includes a first receiver, a second receiver, a first delay line, and a second delay line. The first receiver receives an input signal using a first supply voltage. The first delay line delays an output of the first receiver based on a first delay control signal and a first complementary delay control signal to generate a received signal. The second receiver receives a clock signal using a second supply voltage. The second delay line delays an output of the second receiver based on a second delay control signal and a second complementary delay control signal to generate a received clock signal. Delay amounts of the first and second delay lines are complementarily changed based on the first and second supply voltages.
