Abstract
An integrated circuit chip comprising a number of semiconductor components exhibiting parasitic components through which a short-circuit between the circuit supply voltage and ground could occur, wherein said semiconductor components are distributed in elementary blocks, each elementary block being independently connected, for its power supply, to the supply or ground lines of the main supply network of the integrated circuit by a current-limiting device capable of stopping a short-circuit starting in the considered block, and each block being sized so that logic errors occurring in this block are correctable by error-correction means.
