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

A semiconductor apparatus comprising:

• a first receiver configured to receive an input signal using a first supply voltage;
• a first delay line configured to delay 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;
• a second receiver configured to receive a clock signal using a second supply voltage;
• a second delay line configured to delay 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;
• a first voltage detection circuit configured to receive the first supply voltage as a positive input signal, to receive the second supply voltage as a negative input signal, and to compare the levels of the first and second supply voltages to generate the first delay control signal and the first complementary delay control signal;
• and
• a second voltage detection circuit configured to receive the second supply voltage as a positive input signal, to receive the first supply voltage as a negative input signal, and to compare the levels of the first and second supply voltages to generate the second delay control signal and the second complementary delay control signal.
