Abstract
A semiconductor device includes a flag signal generation circuit and a power-down signal generation circuit. The flag signal generation circuit generates a flag signal which is enabled in response to an operational frequency information signal. The power-down signal generation circuit generates a power-down signal for controlling input of a command in response to the flag signal and a clock enablement signal. A point of time that the power-down signal is generated is adjusted in response to the flag signal.
