Abstract
A method for implementing adaptive error correction in a memory, comprising the steps of (A) decoding a page of data read from a memory, (B) selecting one of a plurality of histograms based on a measured code word error rate of the decoded page and (C) applying an error correction code rate based on the selected histogram. The error correction code rate allows the memory to use a minimum number of error correction bits to provide reliable operation of the memory.
