Abstract
A data output device is disclosed having a first comparator for comparing first output data with arbitrary output data on a bit-by-bit basis and outputting a first pre-flag signal, a second comparator for comparing second output data with the first output data on a bit-by-bit basis and outputting a second pre-flag signal, first and second logic units for performing logic operations with respect to pre-flag signals and data inversion flag signals, a first output unit for inverting or non-inverting and outputting a plurality of bits contained in the first output data in response to the first data inversion flag signal, a second output unit for inverting or non-inverting and outputting a plurality of bits contained in the second output data in response to the second data inversion flag signal, and an output data initializer for, when a no-operation period is generated in a series of data output operations, initializing the arbitrary output data and supplying the resulting data to the first comparator.
