本发明公开了一种使用纠错编码器电路进行纠错的BCH纠错方法。BCH（Bose-Chaudhuri-Hocquenghem）错误校正方法，根据本发明的一个实施例，将正常数据和第一奇偶校验（parity）存储在存储单元阵列的正常数据区域和奇偶校验数据中，存储的正常数据和从数据产生第二奇偶校验数据的步骤，比较第一奇偶校验数据和第二奇偶校验数据，以及用比较的结果检查错误。由于根据本发明实施例的BCH纠错方法和电路通过使用根据本发明的编码器，通过检查错误，便于电路实现所需的校正子生成和多位的并行处理，因此具有减少纠错时间、功耗和布局面积的优点。
The BCH error correction method for error checking using the error-correcting encoder circuit and is disclosed. BCH (Bose-Chaudhuri-Hocquenghem) error correction method according to an embodiment of the present invention the normal data and the first parity (parity) and storing the data in the normal data area and the parity data of the memory cell array, respectively, the stored normal and a step of generating a second parity data from the data, comparing the first parity data and second parity data, and checking errors with the result of the comparison. Because BCH error correction method and circuit according to the embodiment of the present invention in accordance with the present invention by using the encoders, by checking an error, facilitating the circuit required for the syndrome generated implement and the parallel processing of the plurality of bit easy, error correction It has the advantage of reducing the time, power consumption and layout area.
