ABSTRACT:
An output buffer of semiconductor memory device is provided for improving the operation speed and for reducing an output noise. The output buffer in accordance with this invention includes an output node driver having a pull-up transistor and a pull-down transistor for pulling-up or pulling-down an output node; a data input circuit for receiving a data to be outputted from a sense amplifier during a reading operation, in response to an output enable signal and a preset signal; a preset input circuit for receiving an output signal of the output node driver during a preset period before the data is applied to the data input circuit in response to the output enable signal and the preset signal; and a driving circuit for receiving signals produced from the data input circuit and the preset input circuit and for driving the pull-up transistor and the pull-down transistor.
