Abstract
An encoding method for a memory storage apparatus adopting an ECC algorithm is provided. The memory storage apparatus comprises an ECC encoder. The encoding method includes: receiving a write command comprising a write address and a write data; reading an existing codeword; attaching a flip bit to the write data; encoding the write data and the flip bit to generate parity bits based on the ECC algorithm by the ECC encoder and attaching the write data and the flip bit to the plurality of parity bits to generate a new codeword; flipping the new codeword based on a number of bits among selected bits required to be changed from the existing codeword to the new codeword; and writing one of the new codeword and the flipped new codeword to the write address. In addition, a memory storage apparatus using the encoding method is provided.
