Abstract: A time manager controls one or more timing functions on a circuit. The time manager includes a data storage and a time calculator. The data storage device stores a first indication of a performance characteristic of a memory cell at a first time. The data storage device also stores a second indication of the performance characteristic of the memory cell at a second time. The time calculator is coupled to the data storage device. The time calculator calculates a time duration between the first time and the second time based on a change in the performance characteristic of the memory cell from the first indication to the second indication.

Abstract: It is described an electronic circuit chip for an RFID tag. The electronic circuit chip comprises (a) an access circuit configured for coupling the electronic circuit chip to an antenna element of the RFID tag, and (b) a memory device being connected to the access circuit. The memory device is configured for storing a secret value, for making retrievable the secret value, and for deleting the secret value. Deleting the secret value is accomplished if the secret value has been retrieved by means of a first attempt procedure for retrieving the stored secret value. It is further described an RFID tag comprising such an electronic circuit chip and a method for managing the use of a read-only-once secret value by an RFID tag with such an electronic circuit chip.
