Abstract
A method for outputting data in a semiconductor device includes receiving an external clock signal, synchronizing, in a delay locked loop of the semiconductor device, a first internal clock signal to the external clock signal during a read period, synchronizing, in the delay locked loop, a second internal clock signal to the external clock signal during an active period, the second internal clock signal having a period longer than the first internal clock signal, and outputting data synchronized with the first internal clock signal during the read period.
