Abstract
For an encoder for use in a flash memory controller, partial parity blocks generated in the encoder are divided into two parts for further operations, wherein a number of partial parity block(s) of the first part generated earlier is less than a number of partial parity block(s) of the second part. The encoder can reduce the hardware required for the circulant convolution calculation in the encoder, and has high efficiency. In addition, by converting a parity-check matrix to generate an isomorphic matrix, some components in the encoder and the decoder can be further omitted, so as to further reduce the manufacturing cost.
