Abstract:
An error correction circuit of a semiconductor memory device including a memory cell array includes an error correction code (ECC) memory that stores an ECC and an ECC engine. The ECC is represented by a generation matrix. The ECC engine generates first parity data based on main data using the ECC, and corrects at least one error bit in the main data read from. the memory cell array using the first parity data. The main data includes a plurality of data bits divided into a plurality of sub codeword groups. The ECC includes a plurality of column vectors divided into a plurality of code groups corresponding to the sub codeword groups. The column vectors have elements configured to restrict a location of a sub codeword group in which a mis-corrected bit occurs, in which the mis-corrected bit is generated due to error bits in the main data.

Claim (Index 13):
The semiconductor memory device of  claim 10 , wherein:\n the error bits include a first error bit and a second error bit; and when a first sub codeword group of the sub codeword groups includes the first error bit, and a second sub codeword group of the sub codeword groups different from the first sub codeword group includes the second error bit, a first code group of the code groups corresponding to the first sub codeword group includes a plurality of first column vectors, and a second code group of the code groups corresponding to the second sub codeword group includes a plurality of second column vectors, wherein the plurality of first column vectors and the plurality of second column vectors are configured such that a result of a bit-wise exclusive OR operation of each of the first column vectors and each of the second column vectors matches with one of the column vectors in the code groups other than the first code group and the second code group,
