Abstract:
The present invention provides an encoding circuit of a flash memory controller, wherein the encoding circuit includes an auxiliary data generating circuit and an encoder. In the operations of the encoding circuit, the auxiliary data generating circuit is configured to receive a plurality of data chunks to generate auxiliary data corresponding to the data chunks. The encoder is configured to encode the data blocks to generate parity codes according to a parity check matrix, and to use the auxiliary data to replace a portion of the parity codes to generate adjusted parity codes, wherein the data chunks and the adjusted parity codes are written into a flash.
