Abstract
An apparatus for outputting data of a semiconductor memory apparatus, which is capable of varying the slew rate and the data output timing, includes a bias generator that generates a bias having a level corresponding to a set value, a slew rate controller that controls a pull-up slew rate or a pull-down slew rate of input data on the basis of the bias generated by the bias generator, and a data outputting unit that outputs data on the basis of the slew rate controlled by the slew rate controller. Therefore, it is possible to satisfy various operational conditions without changing the structure of the circuit and to correspond rapidly and appropriately with a change of the system, which enables the applied range of the products to be extended.
