A method and apparatus for data bus inversion provides for a data bus having a data bus size value, wherein the data bus size value represents the number of bits transferred across the bus in a single transmission, for receiving a new data value having a plurality of new data bits. The method and apparatus further provide for determining the change bit value by comparing the different new data bits with a plurality of current transmission data bits from a current data value. Furthermore, when the change bit value is equal to one-half the data bus size value, the method and apparatus provides for adjusting at least the plurality of new data bits and/or a data bus inversion bit, based on the determination to assert the plurality of new data bits and the data bus inversion bit closer to a bus idle value.
