Abstract

A semiconductor chip with functions implemented thereon in circuitry has a first region, in which a first group of safety-relevant base functions are implemented in circuitry, and a second region, which is separated from the first region using technological safety measures and in which a first group of monitoring functions that monitor the base functions are implemented in circuitry. It also contains a third region, which is formed on the semiconductor chip and is separated from the other regions using technological safety measures and in which a second group of monitoring functions that monitor the base functions are implemented in circuitry.
