ABSTRACT:
A programmable read-only memory includes a number of programmable memory cells, each of which is formed in a thin layer of semiconductor material which extends on an insulating layer of a semiconductor body. Each programmable memory cell includes a p-n junction diode and an electrically destructible programmation element which are integrally formed in the thin layer of semiconductor material. The programmation element includes a necked-down portion of the thin layer, and this element may also have a p-n junction. The resulting structure yields a memory cell which is simple, highly compact, and which can be easily and reliably manufactured by known methods.
