Abstract
An n channel driver circuit comprised of an N channel MOS transistor is provided in parallel to a driver circuit comprised of a P channel MOS transistor. Normally, n channel driver circuit supplies an internal supply voltage, to activate driver circuit only at the time of current peak. Thus, an insufficient capability of n.sup.- channel driver circuit to supply current is supplemented.
