Methodology for improved bit-flipping decoder in 1-read and 2-read scenarios

摘要

Systems and methods are provided for decoding data. A decoder includes a syndrome memory, a state memory, and decoding circuitry communicatively coupled to the syndrome memory and the state memory. The decoding circuitry retrieves data related to a symbol from the syndrome memory. The decoding circuitry also retrieves data related to the symbol from the state memory. The decoding circuitry processes the data retrieved from the syndrome memory and the data retrieved from the state memory to determine whether to toggle a value of the symbol. The determination is based at least in part on whether the symbol of the data being decoded was previously toggled from an original state.
