Abstract:
A chip having a substrate region having a substrate contact, an RS latch having two complementary nodes representing a storage state of the RS latch, a control circuit having a control input and configured to connect one of the complementary nodes to a supply potential depending on a potential at the control input, wherein the control input is connected to the substrate contact, and an output circuit connected to an output of the RS latch and configured to trigger an alarm depending on the storage state of the RS latch.
