Error correction device, operating method of error correction device, and controller including error correction device

An error correction device includes a low density parity check (LDPC) decoder and an adaptive decoding controller. The LDPC decoder iteratively performs LDPC decoding on data by using a decoding parameter. The adaptive decoding controller calculates an error rate depending on a result of the LDPC de...

Zusammenfassung:	An error correction device includes a low density parity check (LDPC) decoder and an adaptive decoding controller. The LDPC decoder iteratively performs LDPC decoding on data by using a decoding parameter. The adaptive decoding controller calculates an error rate depending on a result of the LDPC decoding and adjusts the decoding parameter depending on the error rate.
