Abstract

See full text

A semiconductor memory is provided which includes a voltage converter supplying an internal supply voltage in proportion to the greater one of two reference voltages to a circuit in the semiconductor memory. The voltage converter includes a circuit which is provided for generating a first voltage whose dependency on an external supply voltage is regulated to a predetermined small value, while another circuit is provided for generating a second voltage whose dependency on the external supplying voltage is larger than the dependency of the first voltage. The voltage converter includes MOS transistors and differential amplifiers interconnected with one another, as well as a voltage dividing circuit. The memory also includes a word line booster for boosting the internal supply voltage.
