Patent ID: 6982869

Claim:
A computer system comprising: an input device; an output device; a processor, coupled to said input device and said output device; and a memory module, coupled to said processor, comprising: a module board having at least one electrical circuit in electrical communication with at least one high density semiconductor package; said at least one high density semiconductor package attached to and in electrical communication with said module board, said at least one high density semiconductor package comprising: a flexible interposer folded around at least one semiconductor die, said interposer including a first surface having a plurality of electrical contacts for electrically connecting said at least one semiconductor die to a substrate, a second surface, and a plurality of vias extending through said interposer from said first surface to said second surface, said at least one semiconductor die having a plurality of bond pads on a surface thereof and a back side surface, said at least one semiconductor die attached to said interposer to form an intermediate packaging structure; and said substrate attached to said intermediate packaging structure and connected to said at least one semiconductor die through said electrical contacts and said plurality of bond pads.
