Abstract: The method involves reading data words of defined length from RAM (1) and writing them in to the page register (8), carrying out the programming process for these data words and then reading the data words from RAM again and the programmed data words from the EEPROM and verifying them, whereby these steps are repeated until the programming of the EEPROM has been completed. Independent claims are also included for the following: an arrangement with a processor for programming and verifying EEPROM pages, a computer program product for programming and verifying EEPROM pages and a computer-readable memory medium for an inventive computer program product.

Abstract: In order further to develop a circuit arrangement (100) for electronic data processing - having at least one non-volatile memory module (10) for storing data to be protected against unauthorized access by means of encryption or decryption -having at least one code R`ead! O`nly!M`emory! module (20) for storing and/or supplying at least one R`ead!O`nly!M`emory! code; and -having at least one code ROM module interface logic circuit (22) assigned to the code ROM module (20) and an en-/decryption method based thereon in such a way that on the one hand the key code may be changed for different controller versions with different ROM codes and on the other hand the length of the key code is not limited, it is proposed that the data assigned to the memory module (10) be encrypted or decrypted by means of the ROM code supplied by the code ROM module (20).
