Abstract

A TTL compatible erasable programmable read-only memory (PROM) which uses a single n-channel device having a floating gate for each memory cell. The entire memory including the periphery circuits, are disposed on a silicon substrate. Only a single externally generated high voltage input or "pin" is required for programming.
