A clock generation circuit and a method for generating a clock are provided to generate a clock with the same period as an external clock as an internal clock. A clock generation circuit generates a clock used in outputting a data signal to a data pin. The clock generation circuit includes a divider part(100) and a clock generation part(200). The divider part divides an internal clock generated by an external clock. The clock generation part generates a clock with the same period as the external clock as having constant duty by assembling divided clocks divided through the divider part.
