A data output control circuit controls a data output in a read operation. A data output control method includes a count shifting mode and a delay mode and can be used in low and high frequency operations, so that a data output can be stably controlled in a broad frequency range. The data output control circuit includes: a low frequency mode controller a high frequency mode controller and a selector selecting any one of first and second command signals through CAS latency information to be output as a data output control signal.
