Abstract

PURPOSE:To prevent the natural vanishing of information due to ultraviolet rays easily by sealing a window for erasing the information of a read-only memory element, which can be erased, by coloring glass sufficient for preventing the natural vanishing of information. CONSTITUTION:The read-only memory 12 is placed on a ceramic base body 11 with an external connecting lead 13, and a ceramic cover body 15 with the colored glass 14 sufficient for preventing the natural vanishing of information is fixed onto the base body 11 as window glass for ultraviolet-ray irradiation and airtight sealing. Accordingly, the natural vanishing of information due to ultraviolet rays is easily prevented, and there is no trouble in the erasing of information and second writing.
