스마트카드의 비휘발성 메모리로서 많이 쓰이는 EEPROM 은 사용에 주의해야 할 특성이 있다. 한번에 읽기, 쓰기에 접근할 수 있는 양의 개념으로 페이지가 쓰이면서, 특히 쓰기에서 여러 페이지에 걸친 부분에 접근할 매는 여지없이 기다려야 하는 블록시간이 존재한다. 이 블록 시간으로 하여 EEPROM 의 메모리 관리는 이음새 없는 하나의 덩어리 공간으로 다룰 때 오버로드를 포함하게 되어 특히, 사용자와 직접적인 통신인 되는 장치에 들어가는 EEPROM 일 때는 그 응답시간에 영향을 주게 되는 부분이다. 또한 쓰기에 있어 EEPROM 의 각 부분은 회수 제한이 있기 때문에 이를 고려해서 본 논의는 비휘발성 메모리로서 EEPROM을 대상으로 그 효율적인 관리 기법을 제안한다.
