Abstract:
A flash memory error correction method and apparatus is provided. The method includes determining a first data bit in a flash memory page, where the first data bit corresponds to different data respectively in the data obtained by reading the flash memory page using the (n+1) th  read voltage threshold and the data obtained by reading the flash memory page using the m th  read voltage threshold; and then reducing a confidence level of the first data bit in the data obtained by reading the flash memory page using the (n+1) th  read voltage threshold; and performing, according to an adjusted confidence level of the first data bit, error correction decoding on the data obtained by reading the flash memory page using the (n+1) th  read voltage threshold. Present disclosure effectively improves a success rate of error correction decoding, thereby significantly improving performance of an SSD storage system.

Claim (Index 18):
The system of  claim 13 , wherein the controller is further configured to perform, using a low-density parity-check (LDPC) code, error correction decoding on the data obtained by reading the flash memory page using the (n+1) th  read voltage threshold.
