ABSTRACT:
A method and system transfer read data from a memory device having a data bus and a data masking pin adapted to receive a masking signal during write operations of the memory device. The method includes placing a sequence of read data words on the data bus and applying a data bus inversion signal on the data masking pin, the data bus inversion signal indicating whether the data contained each read data word has been inverted. Another method and system transfer data over a data bus. The method includes generating a sequence of data words, at least one data word including data bus inversion data. The sequence of data words is applied on the data bus and is thereafter stored. The data bus inversion data is applied to invert or not invert the data contained in the stored data words.
