Abstract
A semiconductor memory device can optimize the layout area and current consumption based on multi-phase clock signals which are generated by dividing a source clock signal using a reset signal without a delay locked loop and a phase locked loop in order to have various phase information of low frequencies and different activation timings with a constant phase difference.
