Abstract
A semiconductor memory device that includes a command decoder, a refresh controller, an oscillator and a delay unit. The command decoder generates a self refresh command, and the oscillator generates an oscillation signal. The refresh controller generates a refresh control signal and a recovery signal in response to the self refresh command and the oscillation signal. The delay unit transitions internal nodes included in the delay unit that are not transitioned during a refresh period in response to the refresh control signal and the recovery signal.
