Semiconductor memory card, and program for controlling the same

The invention claims a semiconductor memory card, wherein electronic commerce application data writing store the semiconductor memory card having enough storage capacitor. Expanded for preventing groove module (TRM 1) EEPROM 3 EC application is area. The device for expanding, and is located on the district according TRM 1 beside the flash 2 with point to the EC device, and 3 setting the partition meter of internal EEPROM. Layer the partition meter of TRM 1, therefore is of TRM 1 CPU 7 of access the partition meter for with. The access area of each to an limiting to 1 TRM CPU 7, therefore improving content according secrecy camera.
