ABSTRACT:
A dynamic semiconductor memory device includes data output lines (D, D), a data output buffer (12), a column enable buffer (9), and an output enable buffer (11) for generating an output enable signal (OE) to enable the transmission of data from the data output lines to the data buffer. The output enable buffer is driven by the clock signals of the column enable buffer. An output disabling circuit (13) is provided to stop the generation of an output enable signal by the output enable buffer when the output enable buffer is not being driven by the column enable buffer. As a result, the data output buffer assumes a high-impedance state when a power supply is turned on.
