Abstract
A semiconductor memory device, which performs refreshing for data retention, provided with a power down mode that stops refreshing. The device includes a request generation circuit, which generates a refresh request signal with an oscillation signal generated by an oscillation circuit. The oscillation circuit stops generation of the oscillation signal in response to a power down mode entry signal. This reduces the current consumption of the semiconductor memory device.
