ABSTRACT:
A semiconductor integrated circuit configured of a DRAM or the like has a function of generating a step-up voltage and supplying it to a plurality of semiconductor devices. During the period when a burn-in test is conducted, the input voltage of a precharge portion for precharging a step-up node for outputting the step-up voltage is clamped to a predetermined level by a precharge input voltage clamping unit. The precharge input voltage clamping unit prevents the step-up voltage level across the step-up node from excessively increasing during the burn-in test.
