<p>In order to further develop a circuit arrangement ( 100 ) for electronic data communication, comprising-at least a non-volatile memory module ( 10 ) for storing data, and-at least an interface logic ( 20 ) associated with the memory module ( 10 )-for addressing the memory module ( 10 ) and-for writing data to the memory module ( 10 ) or-for reading data from the memory module ( 10 ), together with a related method for registering light attacks on the non-volatile memory module ( 10 ), in such a way that, firstly, the light attack is recognized immediately and reliably regardless of whether an access, in particular a read access, to the memory module ( 10 ) is taking place or not and, secondly, the entire address space of the memory module ( 10 ) is covered as uniformly as possible in this regard, it is proposed that at least a monitoring arrangement ( 22 ) provided for monitoring the memory module ( 10 ) is associated with the interface logic ( 20 ), by means of which monitoring arrangement ( 22 ) an irradiation of the memory module ( 10 ) with at least a light source [so-called "light attack"] can be detected and/or registered and/or signaled in a test mode (T) in which no write or read access to the memory module ( 10 ) takes place.</p> |
