The data carrier which has the detection expedient which detects the change of the information which is remembered with memory expedient

摘要

Modification possible information (i) the 1st memory expedient which modification possibly is remembered the circuit which it has (5) (2) is offered the circuit (2) with environmental parameter. Environmental parameter operates in 1st memory expedient (5). In 1st memory expedient (5) has information of inspection (TI) the inspection memory territory which is remembered (7), furthermore, information of reference (RI) in order not to be able to modify, the 2nd memory expedient which is remembered (16) has, information of the inspection which reads out from 3rd, 1st memory expedient (TI) with 2nd memory expedient (16) from information of the reference which reads out (RI) the detection expedient which is supplied (19) has. Detection expedient (19), information of the detection which reads out (TI) with information of reference (RI) borrowing help, as information of the inspection which originally is remembered by the environmental parameter which operates in 1st memory expedient (5) (TI) detected the fact that it is modified, it is designed.
