ABSTRACT:
A data output circuit includes a plurality of drivers configured to be turned on/off according to impedance codes to output data to an output node. The impedance codes are divided into a first group having a value to turn on the drivers, and a second group having a value to turn off the drivers, and at least some of the drivers controlled by the second group are turned on during a pre-emphasis period.
