Abstract
An electrically erasable programmable read-only memory (E.sup.2 PROM) is provided which utilizes an inhibit voltage applied to unselected word lines during writing to prevent writing in unselected rows. In the preferred embodiment, each memory cell of the E.sup.2 PROM array consists of a single floating gate field effect transistor. The E.sup.2 PROM of the present invention provides for row erasure and single bit writing.
