Abstract
A controller for controlling an operation of a semiconductor memory device includes an error correction block and a block manager. The error correction block may perform an error correction operation on read data received from the semiconductor memory device. The block manager may analyze a result of the error correction operation and selectively perform defect processing on a target memory block in which the read data is stored, based on a number of error correction units in which an error correction failure has occurred, among a plurality of error correction units included in the read data.
