摘要：Apparatuses and methods for performing a data bus inversion operation (DBI)are described. An example apparatus includes a DBI circuit configured to, in parallel,
determine preliminary DBI bits based on a block of data. Individual preliminary DBI bitsare associated with respective sub-blocks of the block of data. The DBI circuit is furtherconfigured to serially determine DBI bits based on the preliminary DBI bits. Individualones of the DBI bits are associated with respective ones of the sub-blocks. The DBI circuitis further configured to invert bits of individual sub-blocks responsive to the respectiveassociated DBI bits having a particular logical value to provide DBI data. The apparatusfurther includes data outputs configured to serially output sub-blocks of the DBI dataand the DBI bits.
