Data Writing to Non-Volatile Memory |
摘要 |
PCT No. PCT/GB94/00775 Sec. 371 Date Feb. 3, 1995 Sec. 102(e) Date Feb. 3, 1995 PCT Filed Apr. 13, 1994 PCT Pub. No. WO94/24673 PCT Pub. Date Oct. 27, 1994A method of writing data to non-volatile memory such as electrically erasable programmable read only memory (EEPROM) in a smart card provides a write status region of EEPROM which is examined on each reset of the card. If the preceding write operation was unsuccessful, perhaps because of deliberate manipulation of the card, a recovery procedure is implemented. If recovery is successful, the card operation can be run. Otherwise the card is unusable. |
