Error correction circuit of semiconductor memory device and semiconductor memory device including the same
An error correction circuit includes ECC encoder and an ECC decoder. The ECC encoder generates, based on a first main data obtained by selectively shifting data bits of a main data based on a LSB of a row address, a parity data using an ECC and stores a codeword including the main data and the parity data in a target page. The ECC decoder generates a syndrome based on a second main data obtained by selectively shifting data bits of the main data based on the LSB of the row address, the parity data and a parity check matrix based on the ECC, and corrects a single bit error or corrects two bit errors when the two bit errors occur in adjacent two memory cells based on the syndrome. The mis-corrected bit is generated when the multiple error bits are present in the main data. |
