ABSTRACT:
A semiconductor memory device having a plurality of banks performs a refresh operation in sequence to each bank whether the refresh operation is required for all or less than all of the banks. The semiconductor memory device includes an extended mode register set containing a refresh information of each bank; and a bank refresh block for supporting a refresh operation performed in sequence to each bank in response to the refresh information of each bank.
