ABSTRACT:
A single-transistor non-volatile memory cell MOS transistor with a floating gate and a control gate using two levels of polysilicon and a tunnel dielectric that overlaps the drain area wherein a tunneling of charge can take place between the drain and the floating gate by means of a system of applied voltages to the control gate and drain.
