A local decoder controlling activation of each word line includes a first transistor connected between first and second nodes, a second transistor connected between a power-supply voltage and the first node, and an inverter driving a word line with the power-supply voltage or a ground voltage in accordance with the voltage of the first node. When a corresponding word line is activated, the second node is set at the ground voltage while the first transistor is turned on. In a burn-in test, a burn-in control circuit forcibly turns off the second transistor in a local decoder corresponding to a word line to be activated.
