Abstract
An external clock enable signal is taken in accordance with a first internal clock signal from clock buffer circuit from which an input buffer enable signal is generated to be input to input buffer circuit. Current path in the input buffer circuit is shut off in accordance with the input buffer enable signal. Since the state of the input buffer enable signal is changed in synchronization with the rise of the internal clock signal, the set up time of the external signal can be sufficiently ensured while current consumption of input buffer circuit can be reduced.
