Abstract
In a highly integrated semiconductor memory device, apparatus for setting a stress mode without applying a stress voltage from the exterior is provided. A triggered time point T.sub.S to a stress mode can be set by greatly raising an internal supply voltage when the external supply voltage is raised to a voltage over the stress voltage.
