A semiconductor memory device is used for outputting data synchronously with rise and fall phases of the reference clock, and includes: a first storage section for storing only the data for the rise-phases of the reference clock and successively outputting the data as read data; a second storage section for storing only the data for the fall-phases of the reference clock and successively outputting the data as read data; and an outputting circuit placed close to a terminal for outputting data externally, for receiving data forwarded from the first and second storage sections and outputting the received data successively according to the rise and fall edges of the reference clock. Of the first and second storage sections, the storage section that stores read data to be output first during a read operation is placed closer to the terminal than the other storage section.
