An error detection and correction device includes a decision-feedback equalizer (DFE), a decision circuit, an error detection circuit, and an error correction circuit. The DFE equalizes a data signal to generate a first equalized signal. The decision circuit performs hard decision upon the first equalized signal to generate a symbol decision signal. The error detection circuit performs forward error detection at symbol positions of consecutive symbols included in the symbol decision signal to detect a head position of suspicious error that affects at least one symbol in the symbol decision signal. The error correction circuit performs error correction upon the symbol decision signal in response to the head position of the suspicious error that is detected by the error detection circuit.
