Claim Text:
1. A method of accumulating soft information of a nonvolatile memory storage module for use in LDPC (Low-Density Party Check) decoding of a codeword stored in the nonvolatile memory storage module, the method comprising: performing a plurality of reads of a cell of a nonvolatile memory storage module to generate a plurality of soft reads associated with a bit stored in the cell; accumulating the plurality of soft reads by summing the number of soft reads having a particular logical value to generate an accumulated soft read associated with the bit stored in the cell, wherein the accumulated soft read has a numerical value equal to the sum of the number of soft reads having a particular logical value; and converting the accumulated soft read into a log-likelihood ratio (LLR) for use in LDPC decoding of a codeword stored in the nonvolatile memory storage module.
