Abstract: A PAM-4 communication process divides a full burst of raw data into two half bursts, extracts a bit from each half burst and communicating the extracted bit on a DBI line, and encodes the remaining bits of the half burst to avoid maximum transitions between PAM-4 symbols on a data line.

Abstract: Techniques for limiting the growth of errors in decoded data words that arise from bit errors incurred during transmission. The growth of 3+ bit errors in the decoded data word is limited at the expense of a higher number of two bit errors, which are correctable using practical error correcting codes.

Abstract: A circuit includes a splitter to extract L bits from each of a plurality of N-bit transmissions on a data bus, a decoder to generate output data comprising N-L bits of each N-bit transmission, and a delay circuit to apply the L bits for a previous transmission to control the inversion of a current transmission at the decoder.
