PROBLEM TO BE SOLVED: To provide a semiconductor memory device in which an exclusive pin for performing switching of a mode can be unnecessitated, and the number of pins can be decreased. SOLUTION: The semiconductor memory device is provided with a memory cell array 10 provided with a plurality of memory cells MC, a burst circuit 31 generating a mode control signal BST, and a control circuit 19 provided with a refresh command detecting circuit 33 sharing a signal line 34 in which the mode control signal is transmitted with the burst circuit, the refresh command detecting circuit 33 performs refresh operation for the memory cell array when the mode control signal is at a first level.
