Abstract
Methods of reading data from storage devices may include reading data stored in the storage device using normal read voltages; performing a first low density parity check (LDPC) decoding based on the read data; generating reliability bits of each of read bits according to the decoding result, the read bits being bits of the read data; and performing a second low density parity check (LDPC) decoding based on the read data and the reliability bits to perform a first error correction on the read data.
