Abstract
An erase voltage control circuit for an electrically erasable non-volatile memory cell having a control electrode and a first electrode. The circuit includes negative voltage generator means for generating a negative erase voltage to be supplied to the control electrode of the memory cell and means for electrically coupling the first electrode to a voltage supply. The circuit further includes control means for selectively deactivating the negative voltage generator means when a current supplied by the voltage supply to the first electrode of the memory cell reaches a predetermined value.
