Abstract
A programmable transistor is provided adjacent to a programmable read only memory. A latch is used in conjunction with the programmable transistor and data is written into the latch. If the programmable transistor is programmed the output of the latch will be modified, however, if the programmable transistor is not programmed the output of the latch will not be modified when it is read. The programming pads used to program the programmable transistor are severed so they are no longer functional once the programmable transistor has been programmed. Therefore if someone erases the programmable read only meory the programmable transistor is also erased and cannot be reprogrammed.
