Abstract
Data for switching a slew rate of a data output circuit included in a data input/output circuit between a slew rate in a normal mode and a slow slew rate is stored in a mode register. According to the data stored in mode register, a slew rate setting signal is generated. According to a slew rate switching circuit, the slew rate of the data input/output circuit is switched between a slew rate in the normal mode and a slow slew rate slower than the slew rate in the normal mode. A data output circuit is achieved which occupies a small area, is capable of setting a slew rate slower than the slew rate in a normal mode and outputting data without causing an erroneous operation with a low consumption current even when the slew rate is adjusted.
