ABSTRACT:
This invention discloses EEPROM which increases an erasing voltage V.sub.pp to be applied in a data write cycle by increasing an avalanche breakdown voltage between a source region and a semiconductor substrate in order to improve erasing efficiency, and employs a structure which strengthens the electric field at the edge of a drain region in order to let hot carrier be easily generated and to improve writing efficiency.
