Abstract
An integrated circuit including: a semiconductor substrate of a first conductivity type having at least one well of a second conductivity type laterally delimited, on two opposite walls, by regions of the first conductivity type, defined at its surface; at least one region of the second conductivity type which extends in the semiconductor substrate under the well; and a system for detecting a variation of the substrate resistance between each association of two adjacent regions of the first conductivity type.
