Abstract

See full text

A non-volatile semiconductor memory device includes a semiconductor substrate, a memory cell including source and drain regions formed in a surface region of the semiconductor substrate, and a first gate insulating film, a charge storage layer, a second gate insulating film, and a control gate sequentially stacked on the semiconductor substrate, the memory cell being capable of electrically rewriting data by exchanging charges between the charge storage layer and the semiconductor substrate, and a means for applying a high potential to the semiconductor substrate and an intermediate potential to the control gate in a first data erase operation, and applying a high potential to the semiconductor substrate and a low potential to the control gate in second and subsequent data erase operations, thereby removing electrons from the charge storage layer.
