A welding jig device is used for forming a part by welding a plurality of members together, and includes a jig on one side having a joint face on one side, which is adapted to contact one of faces exposed on the outer surface sides of the plurality of members overlaid one on top of the other, and an opening on one side corresponding to a portion of desired welded portions of a part; and a jig on another side having a joint face on the other side, which is adapted to contact another face of the faces exposed on the outer surface sides of the plurality of members W, and an opening on the other side corresponding to another portion of the desired welded portions of the part and not corresponding to the opening on the one side.

To improve the reliability of controlling overwriting of a nonvolatile memory in a data processing semiconductor device. In a data processing semiconductor device, a control unit which controls reading, writing, or erasing of data in a rewritable nonvolatile memory area has an operation mode that, referring to the input temperature data, controls a temperature range in which writing or erasing of data is performed to be narrower than the temperature range that allows reading of data in the memory area.
