Patent ID: 7633146

Claim:
A memory card detachably mountable to an electronic apparatus, said memory card comprising: a substrate of an insulating material having a first main surface and a second main surface opposite to said first main surface; conductive layers provided on said first main surface of said substrate; a plurality of external electrode terminals exposed to said second main surface of said substrate; conductive portions electrically connecting said conductive layers with corresponding ones of said external electrode terminals; a set of semiconductor chips including a memory chip and a control chip fixed on said first main surface and connected electrically with corresponding ones of said conductive layers; and a layer of an encapsulating insulating material covering said first main surface of said substrate as well as said set of semiconductor chips and conductive layers, wherein said layer of the encapsulating insulating material has an exposed flat surface which represents a second main plane surface of the finished memory card, and said second main surface of said substrate with said plurality of external electrode terminals represents a first main plane surface of the finished memory card with the external electrode terminals exposed to said first main plane surface of the finished memory card so that said plurality of exposed external electrode terminals are brought in contact with corresponding electrode terminals of the electronic apparatus when the memory card is detachably mounted to the electronic apparatus.
