Abstract
A semiconductor memory apparatus includes a DBI calculation block, an inversion latch block, an inverted data selective output block, and a pipe latch block. The DBI calculation block performs a DBI calculation and outputs a DBI result signal based on a result of the DBI calculation. The inversion latch block inverts data and outputs the inverted data when a DBI enable signal is enabled. The inverted data selective output block outputs the inverted data as a data inversion signal in response to the DBI result signal and a pipe input signal. The pipe latch block receives the data, which is not inverted, and the inverted data, and outputs one of the data and the inverted data according to the result of the DBI calculation.
