ABSTRACT:
A programmable unit is described. The programmable unit has a memory device and a read protection device by which it is possible to prevent data from being read from the memory device. The described programmable unit is distinguished in that the read protection device prevents data from being read from the memory device only when a locking tag is set, and in that the programmable unit sets or does not set the locking tag automatically as a function of the operating mode that the programmable unit is in.
