摘要:
A semiconductor memory device includes a memory which comprises a confidential information area storing confidential information and a flag. A controller reads the flag from the memory when instructed to erase or write data in the confidential information area, determines whether the flag is set, erases or writes data in the confidential information area when the flag is clear, and abandons a process requested by an erase or write instruction when the flag is set. An authenticator uses data in the confidential information area to execute an operation for authentication. A management information area may store management information for associated pages. The flag may include a bit string and a complementary bit string to improve reliability of the flag. The confidential information area may store dummy data when the memory is used for uses other than an application with an authentication function, so no problem arises using a normal controller.

According to one embodiment, a semiconductor memory device includes a memory which comprises an area accessible from outside and a confidential information area storing confidential information and a set flag. A controller reads the flag from the memory when instructed to erase data in the confidential information area, determines whether the flag is set, erases data in the confidential information area when the flag is clear, and abandons process requested by the data erase instruction when the flag is set. An authenticator uses data in the confidential information area to execute operation for authentication.

A communication system and a statistical processing method capable of performing statistical processing of user attribute distribution information on a sector-by-sector basis. An acquisition unit acquires, from each of a plurality of mobile equipments, a sector ID of a sector where located and a user identifier being, which is identification information of a mobile equipment, and the subscriber location information storage unit stores the acquired sector IDs in association with mobile equipments. Then, the sector level attribute distribution derivation unit aggregates the number of mobile equipments for each attribute of mobile equipments on a sector basis indicated by the sector ID based on subscriber information stored in the subscriber attribute information storage unit and location information stored in the subscriber location information storage unit. It is thereby possible to grasp statistical information for each attribute of mobile equipments on a sector-by-sector basis.
