Memory control device with configurable ECC (Error Correction Code) parameter

The invention discloses a memory control device with a configurable ECC (Error Correction Code) parameter, which can be used for configuring the data block length and the error correction capability of an ECC module within a certain range. The device is internally provided with an ECC code data block length register and an ECC code error correction capability register which are respectively used for storing the data block length and the code error correction of an ECC code. In practical application, a user sets the two registers through a CPU according to the requirement of a flash memory. The memory control device is also provided with a generated multinomial register or a generated multinomial list and an iteration initial value register set or an iteration initial value list, and corresponding encoding and decoding operations are carried out through the generated multinomial register and the iteration initial value register set based on numerical values in the ECC code data block length register and the EC
