Internal voltage fall-down circuit

摘要

An internal voltage fall-down circuit includes a reference voltage generating section for variably generating an optimum reference voltage level of which is compensated for depending on changes in the present reference voltage before fuse blowing, a reference voltage transforming section for receiving the reference voltage from the reference voltage generating section and then transforming the reference voltage into voltage for a normal mode or a stress mode which are presently set, and a driver section for providing a signal from the reference voltage transforming section to an internal circuit as an internal supply voltage.
