Error correction coding in non-volatile memory

摘要

A method includes encoding data bits into codewords according to a first error correction encoding scheme. The method includes storing the codewords into a memory and generating a combined codeword by encoding, at the memory, the codewords according to a second error correction encoding scheme to generate parity bits of the combined codeword. The method includes, after storing the codewords into the memory, storing the parity bits of the combined codeword into the memory.

1. A method comprising:
encoding first data according to a first error correction encoding scheme to form a first codeword; encoding second data according to the first error correction encoding scheme to form a second codeword; storing the first and second codewords into a memory; encoding, at the memory, the first and second codewords according to a second error correction encoding scheme to generate parity bits of a combined codeword including the first and second codewords; and after storing the first and second codewords into the memory, storing the parity bits of the combined codeword into the memory.
