Abstract

A memory device and an arrangement are provided for safeguarding safety-critical program parts against inadvertent execution. At least one program part is executed in a predetermined chronological sequence. At a certain time in the execution, a pattern is generated. At least at one later time, a check is then performed to determine whether the pattern is present. If the pattern is not present, the execution of the respective program part is terminated.
