ABSTRACT:
A voltage level converting circuit for use in semiconductor devices including memory such as ROMs, PROMs and EPROMs comprises an input terminal to which an input signal is applied, a voltage level detecting circuit for detecting the voltage level of the input signal received by the input terminal and supplying an output signal of the voltage level determined in response to the level of the input signal, an inverter connected to the voltage level detecting circuit and a CMOS device having a pair of outside source/drain terminals connected between the input terminal and a first reference voltage, a gate terminal connected to the output of the inverter and the inner interconnected source/drain terminals connected to an output terminal of the circuit.
