30 Apr 1991TL;DR: In this paper, the authors propose to reduce the writing frequency of an information carrier by introducing checking steps before the actual writing operation and selective writing dependent on the result of the check.
Abstract: Information carriers which contain an electrically erasable programmable memory (EEPROM) suffer from the problem that the utilisation period of the carrier is greatly restricted if data in a fixed address space of the EEPROM have to be changed frequently, since the service life of the individual cell of the EEPROM is limited by the number of its write cycles. By reducing the writing frequency, for example by introducing checking steps before the actual writing operation and selective writing dependent on the result of the check, the utilisation period of the information carrier can be prolonged.
