Abstract
A memory device includes a delay locked loop that generates a first code for delaying a reference clock in a first operation mode that is a normal operation mode, generates a second code for delaying the reference clock in a second operation mode that is a refresh mode, and delays the reference clock in response to one of the first and second codes depending on one of the first and second operation modes, and a data output circuit that outputs a data strobe signal (DQS) using the delayed reference clock.
