Abstract
A semiconductor device may be provided. The semiconductor device may include a power-down signal generation circuit and a refresh signal generation circuit. The power-down signal generation circuit may be configured to generate a power-down signal which is enabled during a power-down operation period based on a multi-operation signal that is generated by decoding commands. The refresh signal generation circuit may be configured to generate a refresh signal which is enabled during a refresh operation period based on the multi-operation signal and an operation selection signal.
