PURPOSE: An output buffer of a semiconductor device is provided, which has good noise characteristics without speed delay by reducing a maximum current during an operation. CONSTITUTION: A control signal generator(100) generates a pulse signal which becomes active only during a constant interval including a time when read data is transferred. And a buffer(200) outputs by buffering the above read data, and is disabled when the above pulse signal is inputted. The buffering unit comprises a data transmission unit(210) buffering the read data according to a control signal being output from the control signal generator and includes an output driver(220) pulling up or pulling down an output signal of the data transfer part to an output port.
