Abstract
A semiconductor memory device includes a plurality of banks, a sense amplifier, an ECC code generation unit, an error correction unit, a first bus, and a second bus. The banks include a data recording unit in which rewritten data is to be written, and an ECC code recording unit in which an error correction code corresponding to the rewritten data is to be written. The sense amplifier is included in each of the banks and configured to read and write data from and to each of the banks. The ECC code generation unit generates the error correction code. The error correction unit corrects an error of data using the error correction code. The first bus connects the sense amplifier in each of the banks and the error correction unit. The second bus connects the ECC code generation unit and the sense amplifier in each of the banks.
