  • Publication number: 20140223569
    Abstract: An embedded security module includes a security processor, volatile and non-volatile memory, and an interface. The security processor includes transistors formed in one or more semiconductor layers of a semiconductor die, and implements one or more security-related functions on data and/or code accessed by the security processor. The volatile memory is fabricated on the same semiconductor die as the security processor and stores the data and/or code accessed by the security processor. The non-volatile memory includes non-volatile storage cells disposed above each semiconductor layer of the semiconductor die, and securely stores at least one of the data and/or code accessed by the security processor and security information relating to the data and/or code accessed by the security processor. The interface is fabricated on the same semiconductor die as the security processor and provides a communication interface for the security processor.

  • Patent number: 7814396
    Abstract: Checking an error recognition functionality of a memory circuit including a memory that stores a datum, and a check value circuit that executes the error recognition functionality, is performed by a monitoring circuit. The memory circuit provides the datum to the check value circuit, wherein the check value circuit checks the datum provided thereto for errors and outputs an error signal if an error is present. The monitoring circuit is coupled to the check value circuit and influences the check value circuit, the memory circuit or the datum provided to the check value circuit so that the check value circuit discovers an error in a check in a case of correct execution of the error recognition functionality, and outputs an alarm signal if the check value circuit does not output an error signal upon the influence of the monitoring circuit.
