    • 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. The partitioned areas in the memory area of this information storage apparatus are updated at a partition request reflecting the user's intention in accordance with the user's intention.
    • 提供一种信息存储装置,其能够基于用户的意图来设定由存储区域划分而产生的划分区域的数量和大小。 为此,在存储区域中具有不同安全级别的多个划分区域的信息存储装置设置有控制存储区域中的分割区域的地址的区域控制部,控制更新条件的区域更新条件控制部 当更新分割区域的数量或大小时,区域更新判定部分判定请求更新划分区域的数量或大小的分区请求是否满足更新条件,以及区域更新部分,当分区请求满足 更新条件,根据分区请求更新存储区域中的分区区域。 该信息存储装置的存储区域中的划分区域根据用户的意图按照反映用户意图的分区请求进行更新。
