  • SSD device featuring improved decoding
    Patent number: 11880588
    Abstract: A method for decoding, in a solid-state storage device, a read symbol encoded with a Q-ary LDPC code defined over a binary-extension Galois field GF(2r), wherein the read symbol is associated with 2r LLR values each one denoting a symbol probability indicative that the read symbol was equal to a respective possible symbol, the method comprising: (a) associating, with the read symbol, candidate symbols comprising a number of the possible symbols associated with LLR values indicative of highest symbol probabilities; (b) storing the candidate symbols and the associated LLR values in V2C and V_SUM matrices; (c) based on the V2C matrix, performing a check node update procedure to update the C2V matrix; (d1) determining an updating LLR value for each possible symbol associated with the read symbol; (d2) determining, for the V_SUM matrix, an approximated LLR value for each excluded symbol, said determining being based on the LLR value indicative of the lowest symbol probability, and on an offset LLR value; (d3)
