Abstract
In a semiconductor memory device, a refresh circuit outputs a refresh command signal for executing refresh operation. The refresh circuit includes a command-signal activating circuit for activating the refresh command signal, and a determination circuit for determining whether the activated refresh command signal is to be output. The determination circuit determines that the activated refresh command signal is to be output when the semiconductor memory device is in a standby state. Thereby, the semiconductor memory device enables stable refresh operation to be executed.
