Abstract: PURPOSE:To protect data written in a semiconductor memory element without providing a data protecting means by a method wherein a window through which the semiconductor memory element is irradiated with ultraviolet rays or the like is provided in the surface of a package opposite to the mounting member for the package. CONSTITUTION:In a package 3 which houses a semiconductor memory device whose written data are erased by the irradiation with ultraviolet rays or the like, an IC incorporating the memory element is mounted on a mounting member such as an printed wiring board or the like (not shown in a figure) of the package 1 through such a manner that lead wires 3 are soldered to lands formed on the mounting member, and a window 2 is covered with the mounting member. Therefore, external penetrating light such as direct sunlight incident on the window 2 can be blocked by the mounting member, and the data written in the memory element can be erased by irradiating it with ultraviolet rays through the window 2, so that a package can be obtained which can dispence with a means which is used for protecting data against external light which penetrates through the window 2.
