Abstract
An electronic device includes a core circuit configured to store write data and a write parity after outputting read data and a read parity in a data masking operation. The electronic device also includes an error correction circuit configured to correct an error included in the read data, based on the read parity; generate the write parity from the error-corrected read data, input data, and masking data; and generate the write data from the error-uncorrected read data, the input data, and the masking data.
