Abstract:
A method of transferring data by utilizing n data lines where n is a natural number, comprising:a step of specifying at least one block from said n data lines, said certified at least one block including a plurality of data lines less than n; a first decision step of deciding whether or not there is a transition in a data bit sent for each data line by majority with respect to said plurality of data lines included in said specified at least one block, separately from the remaining data lines not included in said specified at least one block; and a second decision step of further deciding whether or not there is a transition in a sent data bit or a sent result by majority with respect to the result obtained by the majority decision in said first decision step and the remaining data lines not included in said specified at least one block or with respect to the result obtained by the majority decision in said first-decision step and a result obtained by a majority decision of the remaining data lines not included in said specified at least one block; in each of said first and second decision steps, when an advantageous decision is obtained by the majority decision in the decision step, deciding polarity of data bits to be a true, using the polarity as a result of the decision step, and inverting all data bits that have been decided by the majority decision; in each of said first and second decision steps, when an advantageous decision is not obtained by the majority decision in the decision step, deciding polarity of data bits to be a false and using the polarity as a result of the decision step, said method further comprising: a step of transferring information about the polarity of data bits as a first redundant inverting signal by utilizing at least one additional data line prepared separately from said n data lines; and a step of reproducing original data bits from the data bits inverted responsively to the polarity of the data bits being a true, in accordance with the information about the polarity of the data bits which is transferred as the first redundant inverting signal after transfer of the data bits.
