Integrated circuit device, information processing apparatus, memory management method for information storage device, mobile terminal apparatus, semiconductor integrated circuit device, and communication method using mobile terminal apparatus

A mobile terminal apparatus comprising:

• a semiconductor integrated circuit device having:
• (a) a memory region;
• (b) a wireless interface for enabling the semiconductor integrated circuit device to perform wireless communication with an external apparatus;
• and
• (c) a wired interface for performing wired communication with the semiconductor integrated circuit device;
• one or more applications allocated to the memory region, wherein the right to access each application is controlled by a personal identification code;
• user input means for inputting, from a user, the personal identification code and other data;
• checking means for:
• (a) transferring, via the wired interface, the personal identification code input from the user input means to the semiconductor integrated circuit device;
• and
• (b) checking the transferred personal identification code with a personal identification code for each application allocated to the memory region;
• access-right control means for giving, as a result of checking by the checking means, a right to the user to access the application in which the personal identification codes match each other;
• wherein the access-right control means:
• (a) sets each application for which the personal identification code is set to be inaccessible in a default setting;
• (b) in response to the personal identification code input from the user matching the set personal identification code, sets the corresponding application to be accessible;
• (c) in response to the personal identification code input from the user matching a set additional personal identification code, sets all applications in the corresponding memory region to be accessible;
• and
• (d) sets all applications to be inaccessible when a predetermined period of time elapses.
