Abstract
A semiconductor device includes an operation control circuit and a mode register activation signal generation circuit. The operation control circuit generates a chip identification storage control signal, a selection identification storage control signal, and a mode register set signal in response to an external set signal and a command. The mode register activation signal generation circuit generates a chip identification and a selection identification in response to the chip identification storage control signal and the selection identification storage control signal. The mode register activation signal generation circuit also generates a mode register activation signal for controlling a mode register set operation in response to the mode register set signal when the chip identification is identical to the selection identification.
