IC card and IC card information processing system using the IC card |
摘要 |
<p>A non-volatile storage (3) and a volatile storage (4) having a shorter access time than that of the non-volatile storage are incorporated in an IC card (5), and the contents of the non-volatile storage is transferred to the volatile storage. In executing processings, an operation/processing unit (1) can access the volatile storage to perform processings at high speeds. Of multiple processing programs of a multi-functional IC card, only a selected program on the volatile storage can be executed.</p> |
