Voltage converter arrangement for a semiconductor memory










Image Number 11 for United States Patent #5402375.

In a voltage converter provided in a semiconductor memory and supplying an internal supply voltage to a circuit in the semiconductor memory, a circuit 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 voltage dividing means. The memory also includes a word line booster for boosting the internal supply voltage.
