ABSTRACT:
A negative-voltage circuit for realizing a flash memory is installed independently and is applied selectively to word lines in response to signals sent from row decoders. Row decoders for specifying word lines need not be installed in the negative voltage circuit. The negative circuit can therefore be reduced in scale.
