OUTPUT TIMING CONTROL CIRCUIT OF SEMICONDUCTOR APPARATUS AND METHOD THEREOF

摘要

An output timing control circuit of a semiconductor apparatus may include a strobe signal generation path configured to control a latency and a delay time of an internal signal, and generate a strobe signal. The output timing control circuit may include a first detection block configured to detect a phase difference of the strobe signal and a clock signal, and control the delay time according to the detected phase difference. The output timing control circuit may include a second detection block configured to detect a latency difference of the strobe signal and the internal signal, and control the latency according to the detected latency difference. The internal signal may be generated according to a preset timing of a command received by the strobe signal generation path.
