摘要:
The subject technology provides reduced overhead in Low Density Parity Check decoding operations. A method includes receiving a hard decode fail indication 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 first read command comprises a first set of read operations. The method includes issuing to the non-volatile memory a second read command for the data using a second set of voltages. The second read command comprises a second set of read operations. The method includes issuing to the decoder, for processing in parallel with the second read command, at least one soft decoding request using soft information based on the first raw data. The method includes receiving from the decoder a success indication of successful decoding.
