摘要
Provided herein may be an error correction circuit, and a memory controller and a memory system. The error correction circuit may include an encoder configured to generate a codeword comprising a message part, a first parity part, and a second parity part, and a decoder configured to perform error correction decoding using read values corresponding to at least a portion of the codeword, wherein, the decoder is configured to perform error correction decoding based on a first or a second error correction ability such that error correction decoding using the first error correction ability is performed using partial read values corresponding to a partial codeword including the message part and the first parity part, and error correction decoding using the second error correction ability is performed using read values corresponding to the entire codeword, and wherein the second error correction ability is greater than the first error correction ability.
