ABSTRACT:
A smart card having integrated circuitry including a single chip embedded microcontroller for controlling all processes and transactions that take place on the card. The single chip embedded microcontroller comprises a processor, a non-volatile erasable PROM communicating with the processor for reading and writing information to and from the PROM, and an error check and correction circuit cooperating with the PROM to correct errors occurring during the read and write operations after the PROM has performed a greater number of read and write cycles than its endurance. By such arrangement, the accuracy of the read and write operations on the smart card is maintained beyond the endurance of said PROM, enabling PROM-based smart cards having endurance on the order of 100,000 read and write cycles.
