Abstract
The disclosure provides a data bus inversion (DBI) encoding device and a DBI encoding method. The DBI encoding device includes a comparator circuit, a first controllable inverting circuit and a second controllable inverting circuit. The comparator circuit checks the number of the different bits between a first raw data and a second raw data. Based on the number of the different bits, the first controllable inversion circuit determines whether to invert a first DBI bit corresponding to the first raw data as a second DBI bit corresponding to the second raw data. The second controllable inversion circuit determines, based on the second DBI bit, whether to adopt the second raw data as a second encoded data corresponding to the second raw data, or invert the second raw data to generate the second encoded data.
