METHOD AND CIRCUIT CONFIGURATION FOR STORING DATA WORDS IN A RAM MODULE

摘要

The invention relates to a method for storing data words in a RAM module that is especially suited for applications that are critical with regard to safety. The inventive method is characterized by the following steps: producing a test bit word from at least one data word when writing the at least one data word into the RAM module, storing the test bit word, reading out test bit word when reading out the at least one data word from the RAM module, regenerating the test bit word from the at least one read out data word, comparing the read out test bit word with the regenerated test bit word and generating an error message if they do not correspond. The invention further relates to a corresponding circuit configuration.
