Abstract:
1. A data storage medium comprising: a semiconductor memory device having a first memory cell array, a second memory cell array, a first terminal connected to the first memory cell array, and a second terminal connected to the second memory cell array; a first wiring, connected to the first terminal, for controlling data write and erase operations of the first memory cell array; a second wiring, connected to the second terminal, for controlling a data write operation of the second memory cell array; an external terminal connected to the second terminal and electrically separated from the first terminal; a support material which supports the semiconductor memory device and the external terminal so that the semiconductor memory device is covered with the support material and the external terminal is exposed from the support material; and certification data that is unique to the semiconductor memory device, stored in the first memory cell array.
