ABSTRACT:
In the present semiconductor device a positive, driving pump circuit is driven by an external power supply potential EXVDD (for example of 1.8V) to generate a positive voltage VPC (for example of 2.4V). A negative pump circuit for internal operation is driven by the positive voltage VPC to generate a negative voltage VNA (for example of −9.2V) required in an erasure or similar internal operation for a word line. The negative pump circuit for internal operation can have a smaller number of stages of pump and hence consume a smaller area than when the circuit is driven by the external power supply voltage EXVDD (for example of 1.8V) as conventional.
