Abstract

A method for detecting the content of a selected memory cell in a memory cell array includes the steps of charging a drain of the selected memory cell to a ground potential, charging a source of the selected memory cell to a predetermined voltage potential, detecting the voltage level on the drain and comparing the detected voltage level with a reference voltage level, thereby producing a comparison result.
