NON-VOLATILE MEMORY ACCESSING METHOD USING DATA PROTECTION WITH AID OF LOOK-AHEAD PROCESSING, AND ASSOCIATED APPARATUS

摘要

A non-volatile (NV) memory accessing method using data protection with aid of look-ahead processing, and associated apparatus such as memory device, controller and encoding circuit thereof are provided. The NV memory accessing method may include: receiving a write command and data from a host device; obtaining at least one portion of data to be a plurality of messages, to generate a plurality of parity codes through look-ahead type encoding, wherein regarding a message: starting encoding a first partial message to generate a first encoded resu applying predetermined input response information to a second partial message to generate a second encoded result, and combining the first and the second encoded results to generate a first partial parity code; and starting encoding the message to generate a second partial parity code, and outputting the first and the second partial parity codes to generate a parity code; and writing into the NV memory.
