METHOD FOR DATA STORAGE IN NON-VOLATILE MEMORY UNIT, METHOD FOR USING INTEGRAL CIRCUIT DEVICE, AND INTEGRAL CIRCUIT DEVICE |
摘要 |
FIELD: information storage equipment. SUBSTANCE: non-volatile memory unit is designed as electrically erasable programmable read-only memory in credit card with embedded microprocessor which provides record storage region in electrically erasable programmable read-only memory, which is tested each time credit card is restored. If previous access operation was not success possibly due to malign card operations, recovery procedure is initiated. If recovery is finished successfully, card application may be started. Otherwise, card is treated as fault. EFFECT: increased functional capabilities. 11 cl, 9 dwg |
