In one embodiment, a latency circuit generates the latency signal based on CAS latency information and read information. For example, the latency circuit may include a clock signal generating circuit generating a plurality of transfer signals and generating a plurality of sampling clock signals based on and corresponding to the plurality of transfer signals such that a timing relationship is created between the transfer signals and the sampling clock signals. The latency circuit may further include a latency signal generator selectively storing the read information based on the sampling clock signals, and selectively outputting the stored read information as the latency signal based on the transfer signals. The latency signal generator may also delay the read information such that the delayed, read information is stored based on the sampling clock signals.
