Abstract
A circuit for providing a programming potential to an electrically programmable read-only memory (EPROM) cell is disclosed. The circuit includes a matched pair of transistors coupled in series and having their gates coupled to a resistor for providing a reference potential. A decoder and latch transfers this potential to another pair of match transistors coupled in series with the EPROM cell. The reference potential is optimized for programming of the cell. The circuit is configured to substantially reduce the load line variations resulting from changes in process and temperature.
