Abstract
A method includes determining a portion of a block of a storage device to read after programming, and reading the portion of the block and determining a maximum error count for the portion of the block. The maximum error count is compared to a threshold. When the maximum error count exceeds the threshold, a code rate of an error correction coding used to program the block is adjusted, or a code rate test is performed on the entire block.
