Abstract: An information storage apparatus capable of setting the number and sizes of partitioned areas resulting from partitioning a memory area based on a user's intention is provided. For this purpose, an information storage apparatus having a plurality of partitioned areas of different security levels in a memory area is provided with an area control section that controls addresses of partitioned areas in the memory area, an area update condition control section that controls update conditions when the number or sizes of partitioned areas are updated, an area update decision section that decides whether a partition request requesting updating of the number or sizes of partitioned areas satisfies the update conditions and an area update section that executes, when the partition request satisfies the update conditions, updating of the partitioned areas in the memory area according to the partition request.

Abstract: Provided is an IC card capable of downloading a card manager even after issuance of the IC card. A first card manager stored in the ROM of an IC card is made to be capable of downloading a privileged application, which is an application having a privilege, and a privileged API in the ROM is made accessible from the downloaded privileged application. When the privileged application accesses the privileged API, the privileged application can operate as the card manager, so that the IC card can download a card manager even after issuance of the IC card.
