Abstract
A semiconductor memory device includes a plurality of banks, a clock input unit configured to receive an external data clock, an internal data clock generation unit configured to receive the external data clock from the clock input unit and generate an internal data clock by delaying the external data clock by a delay amount which changes in correspondence to the number of banks activated among the plurality of banks, and a data buffer unit configured to buffer a data signal in response to the internal data clock.
