Abstract
The subject technology provides reduced overhead in Low Density Parity Check decoding operations. A method includes receiving a hard decode fail indication from a decoder that decoding first raw data read from non-volatile memory in response to a first read command using a first set of voltages failed. The method includes determining a count of available soft decoders of a plurality of soft decoders of the decoder. The method includes determining, based on the count of available soft decoders and a pending number of soft decoding requests, a number of soft decoding requests to issue. The method includes issuing the determined number of soft decoding requests to respective ones of the available soft decoders for soft decoding the first raw data in parallel. The method includes receiving from the decoder a success indication of successful decoding.
