Abstract
A latency control circuit includes a delay unit configured to delay an input signal for a delay corresponding to a phase difference between an external clock and an internal clock and generate a delayed input signal, a delay information generation unit configured to generate a delay information based on a latency information and a delay amount of the input signal caused by a chip including the latency control circuit, a shift unit configured to shift the delayed input signal for a time period corresponding to the delay information in synchronism with the internal clock and an asynchronous control unit configured to selectively control the shift unit to output the delayed input signal without performing a shift operation.
