ABSTRACT:
A semiconductor memory device is capable of easily checking whether banks are overlappingly activated. The semiconductor memory device includes a bank active signal generating unit and an overlap detecting unit. The bank active signal generating unit generates bank active signals for respective different banks in response to an active signal and bank addresses. The overlap detecting unit detects whether the bank active signals of the different banks are overlappingly enabled.
