ABSTRACT:
The present invention relates to an output driver circuit which exhibits a reduced variation in the slew rate of an output signal thereof, irrespective of a variation in temperature occurring during a process carried out by a semiconductor memory device, to which the output driver circuit is applied, or a variation in temperature caused by the operation characteristics of the semiconductor memory device, while exhibiting excellent operation characteristics even in a high-speed operation mode thereof.
