Abstract
A flash memory system may include a flash memory and a circuit for decoding a result of a read operation on the flash memory using a first codeword. The circuit may be configured to generate first soft information of the first codeword. The circuit may be further configured to generate second soft information of a second codeword. The circuit may be configured to generate third soft information based on the first soft information and the second soft information. The circuit may be configured to decode the result of the read operation on the flash memory using the third soft information.
