Abstract: The electronic memory component includes at least one memory cell area, in which physical states (P) representing regular data are presented by a function of representation (A) that is presented by a error correction code, e.g. a Hamming code. At least a further physical state is provided presenting an exception state (L,S) in the error correction code. An Independent claim is also provided for a method for operating the electronic memory component.

Abstract: Method for production of mask-programmed ROMs, using a mask containing several systems, whereby encryption using the mask is carried out in such a way that the systems so produced have different keys. Said keys are contained in ROM fuses. Independent claims are made for a processor arrangement for controlling production of mask-programmed ROMs, a computer program product and a computer readable storage medium for storage of the program product.

Abstract: In a microcontroller (100) the command decoder (15) has access to at least one memory (14). The command decoder may thus be adapted to decode at least one conditional command, while the result of decoding the conditional command is dependent on the contents of said memory (14). The microcontroller according to the invention thus provides the possibility of considerably reducing the programming effort so that both the system performance and the code density can be significantly increased with a small additional number of hardware components.

Abstract: In order to further develop a microcontroller ( 100 ) the programming of which is carried out in at least one machine-dependent assembler language in which the assembler commands, with the exception of conditional program jumps or branches, can be executed in essence independently of data, together with a method for processing the programming of the microcontroller ( 100 ) carried out in at least one machine-dependent assembler language, in such a way that the program running on the microcontroller ( 100 ) is entirely secret and unpredictable, i.e. is not reproducible, for an external observer, it is proposed that the program jumps or branches are executed-in dependence on the state of at least one random number generator ( 10 ) and/or-independently of the internal state of the programming of the microcontroller ( 100 ).

Abstract: A method for transmitting signals from generating functional units to processing functional units of electric circuits. The signals to be transmitted are coded by the generating functional unit and/or modulated and before reception are decoded and/or demodulated by the processing functional unit (3). Transmission of the signals between functional unit (1) and functional unit (3) is achieved by a smart-card controller. An Independent claim is given for an arrangement for signal transmission.

Abstract: Method for controlling access to EEPROMs in which access to the EEPROM, or a part thereof, is controlled using EEPROM fuses. Independent claims are made for: a processor arrangement, such as a smart card, with access to its EEPROMs controlled using fuses; a computer program product and a computer readable storage medium for storage of said program.

Abstract: Method for preventing unauthorized execution of a computer program, whereby during program execution at preset points in the timing cycle signature data is produced, at least a part of the said signature data is compared with externally supplied data and if the data does not match program execution is stopped and the system is reset. The timing cycle is provided by the system clock. The invention also relates to a corresponding processor arrangement, especially a smart card, a computer program product and a computer readable storage medium for storage of said program.
