Semiconductor device card

Abstract

Abstract PURPOSE:To enable two kinds of functions to be used on a same card by a method wherein a large sized card having an opening part and a small sized card capable of being inserted into its opening part, are established. CONSTITUTION:A card inserting part 4 is provided to a frame 2 of a card body 1, and a small card 5 is made capable of being inserted into the card inserting part 4. In the case where the small sized card 5 is inserted, an electrode contact part like to correspond to an outside connector is provided inside the card inserting part 4 of the large sized card 1, and the small sized card 5 is electrically connected to the large sized card 1. Thus, one sheet of a card can be used for various uses and further, for instance, for a jointly used card for RAM and ROM, since the ROM side can be especially exchanged, the use of the ROM card is widened.
