Abstract
A semiconductor memory device capable of reducing current consumption in a partial-array self-refresh (PASR) mode includes a plurality of banks and at least one parity bank. A specific area to be self-refreshed is individually selected from each of some banks selected out of the plurality of banks to perform a self-refresh operation. Data of the specific area to be self-refreshed is verified using an error correction code (ECC) stored in the parity bank.
