Abstract
Various read level control apparatuses and methods are provided. In various embodiments, the read level control apparatuses may include an error control code (ECC) decoding unit for ECC decoding data read from a storage unit, and a monitoring unit for monitoring a bit error rate (BER) based on the ECC decoded data and the read data. The apparatus may additionally include an error determination unit for determining an error rate of the read data based on the monitored BER, and a level control unit for controlling a read level of the storage unit based on the error rate.
