Abstract
A five volt only E.sup.2 PROM cell including metal bit read and bit ground column lines and polysilicon word select and program row lines. An interconnected word select and stacked gate transistor serially connect the bit read and bit ground lines. The cell also includes a tunneling structure, disposed below the program row line, for charging or uncharging a floating polysilicon gate in the stacked gate transistor. The bit ground line is disconnected from ground during the charging and uncharging operations.
