Abstract
Error correction code apparatuses and memory systems are disclosed. The apparatus may include an encoder configured to generate a first result by multiplying bits of the data by a first matrix, divides parity bits into a first parity group obtained by multiplying the first result by a second matrix and a second parity group obtained by an exclusive OR operation of the first result and the first parity group, based on a plurality of polynomials determined based on the second matrix, and multiply the first result and the second matrix to generate one or more first parity bits in the first parity group, perform an exclusive OR operation on the first result and the first parity group to generate one or more second parity bits in the second parity group, and generate a codeword having the bits of the data bits and the parity bits.
