This specification discloses an improvement for a voltage booster circuit. The improvement lies mainly in the use of MISFETs as switching means in a level converting circuit constructed in a complementary MIS semiconductor integrated circuit and therefore the voltage loss due to the conventional switching means can be prevented.
