Abstract
A semiconductor memory device includes a clock buffer which receives an external clock signal and generates a first internal clock signal having a frequency lower than that of the external clock signal and a second internal clock signal having a frequency which is the same as that of the external clock signal. An address buffer, command signal buffer and/or register receive respective input signals at a timing of the first internal clock signal. On the other hand, a data buffer inputs/outputs data at a timing of the second internal clock signal.
