Abstract
A semiconductor memory device includes a clock input block suitable for generating first and second internal clocks in response to an external clock, a clock correction block suitable for generating a data clock by correcting a duty ratio of the first and second internal clocks in response to a signal activated in an initial operation mode of the semiconductor memory device, and a data control block suitable for controlling data in synchronization with the data clock.
