An apparatus comprising a decoder circuit and a memory. The decoder circuit may be configured to generate a single address signal to read a first parity data signal, a second parity data signal and read and/or write systematic information data, a first a-priori-information signal and a second a-priori-information signal. The decoder circuit (i) reads the first parity data signal, the systematic information data and the first a-priori-information during even half-iterations of a decoding operation and (ii) reads the second parity data, the systematic information data and the second a-priori-information during odd half-iterations of the decoding operation. The memory may be configured to store the systematic information data and the first and second a-priori-information signals such that each are accessible by the single address signal.
