Abstract
A method of erasing electrically a programmable memory cell which cell includes a transistor formed in a region of semiconductor material. The transistor has a source region, a drain region, a floating gate, and a control gate. The method includes lowering the control gate to a potential no more negative than 6.5 volts, disconnecting the source and drain regions from any potential source, and placing the region of semiconductor material at a potential no more positive than 8.0 volts.
