  • ROMs are integrated semiconductor memories which are programmed by the manufacturer of such semiconductor memories during the manufacturing process using masks. On the one hand, this means that the user of the ROM cannot carry out the programming process. On the other hand, this means that programming is time-consuming and expensive because the memory manufacturer first has to create a mask corresponding to the program. After programming, the program content of the ROM can no longer be changed. The ROM can therefore not be adapted to redevelopments, further developments and change requests from customers of the device manufacturer using the ROM. For economic reasons, programming a new ROM can only be justified for quantities of around 50,000 or more. An E 2 PROM can be deleted and reprogrammed by the device manufacturer itself.

An E 2 PROM can be added to store at least the operating data.

Since in the solution according to the invention the E 2 PROM does not need to store any sequence program parts and no special device parameters and data, but only operating data for which a relatively small storage capacity is sufficient, the E 2 PROM can also have a significantly smaller storage capacity than with conventional ⁇ Lichen control devices can be selected. So the solution with the Flash EPROM saves four times:
