摘要
A method of characterizing a distribution of a maximum number of errors that first cause uncorrectable error correction code failure for hard low density parity check codes includes selecting a low density parity check code, generating encoded data with the low density parity check code and writing the encoded data to a number of memory blocks, reading the encoded data from the number of memory blocks and determining any pages having a first uncorrectable error correction code failure, determining a number of raw bit errors for each page having a first uncorrectable error correction code failure, incrementing an error count value corresponding to each of the numbers of raw bit errors determined, and repeating the generating, reading, determining, and incrementing steps for a predetermined range of values of a predetermined reliability statistic of the memory blocks.
