Abstract
A semiconductor device includes an error correction circuit and a write operation control circuit. The error correction circuit generates corrected data and an error flag from read data according to whether an error is included in the read data outputted when a read operation is performed. The write operation control circuit generates a write control signal for controlling a write operation based on the error flag.
