A programming module for programming a number of programmable read only memory (PROM) units secured onto a single memory module for use at a selected location of several locations in a programmable controller using a microprocessor operated on a low order logic voltage level and having output address lines, and input/output bi-directional data lines and having means for creating a read signal in a read line and a write signal in a write line. The programming module comprises an input side with terminals connected with the address lines, the data lines, the read line and the write line and an output side having address terminals, program voltage terminals and data terminals for connection with the single memory module to be programmed. The programming module includes its own high level program voltage power source and decoding means for decoding a memory address and applying a programming voltage to a selected PROM unit in response to an address received by the programming module.
A programming module for programming a number of programmable read only memory units secured onto a single memory module for use at a selected location of several locations in a programmable controller using a microprocessor operated on a given logic voltage level and having output address lines, and input/output bi-directional data lines and having means for creating a read signal on a read line and a write signal on a write line, said units being programmable by data at data terminals on said memory units and at locations determined by an address on address terminals of said memory units only when receiving a program voltage at a programming terminal, said programming module comprising:
