Abstract
A semiconductor memory device includes a buffer for outputting an address signal and a decoding circuit having an input for receiving the address signal. A switch electrically connects the buffer to the input of the decoding circuit if a refresh mode specifying signal specifies a first data refresh mode, and electrically disconnects the buffer from the input of the decoding circuit if the refresh mode specifying signal specifies a second data refresh mode different from the first data refresh mode. An activating/deactivating circuit activates the input of the decoding circuit if the refresh mode specifying signal specifies the first data refresh mode and deactivates the input of the decoding circuit if the refresh mode specifying signal specifies the second data refresh mode.
