ABSTRACT:
The present invention intends to provide a semiconductor memory device including a delay locked loop (DLL) circuit capable of generating a duty-corrected delay locked clock. A semiconductor memory device includes: a DLL circuit for generating a delay locked clock through a delay locked operation; and a duty-correction circuit for correcting a duty ratio of the delay locked clock by using the delay locked clock and a divided clock generated by dividing the delay locked clock by an even value.
