Abstract

A system and method for regulating the erase saturation in a semiconductor memory is disclosed. More particularly, the present invention measures the under-erase and over-erase condition of all SONOS transistors in an array of non-volatile SRAM cells and corrects the erase voltage to prevent over-erase and under-erase.
