ABSTRACT:
A semiconductor integrated circuit which converts power-supply voltage applied from outside into optimum voltage for operating an internal circuit at the frequency of an internal clock in response to a multiplication control signal supplied to a PLL circuit from outside to generate the internal clock for operating the internal circuit by dividing a clock supplied from outside or by judging the cycle of an internal clock generated by dividing an external clock so as to supply the optimum voltage to the internal circuit.
