Abstract:
1. A module, comprising: a module card having first and second opposed surfaces, each extending in a first direction and a second direction transverse to the first direction, and a plurality of parallel exposed edge contacts adjacent an edge of at least one of the first and second surfaces configured to mate with corresponding contacts of a socket, the module card having first and second apertures each extending between the first and second surfaces; first and second microelectronic elements, the first microelectronic element having a first surface facing the first surface of the module card and a second surface opposite therefrom, the first microelectronic element having a lateral edge extending between the first and second surfaces thereof and extending in the second direction, the second microelectronic element having a front surface facing the first surface of the module card, the front surface of the second microelectronic element facing and partially overlying the second surface of the first microelectronic element and attached thereto, the front surface of the second microelectronic element projecting in the first direction beyond the lateral edge of the first microelectronic element, chip contacts of the first microelectronic element being exposed at the first surface of the first microelectronic element, chip contacts of the second microelectronic element being exposed at the front surface of the second microelectronic element and disposed beyond the lateral edge of the first microelectronic element, the second microelectronic element having first and second opposed edges extending between the front and rear surfaces of the second microelectronic element and extending in the second direction, the front surface of the second microelectronic element having a first outer region adjacent the first edge, a second outer region adjacent the second edge, and a central region disposed between the first and second outer regions, each of the first and second outer regions and the central region having equal width such that the central region extends a middle third of a distance between the first and second edges, the chip contacts of the second microelectronic element being disposed in the central region; and first wire bonds extending through the first aperture and coupled to the chip contacts of the first microelectronic element, and second wire bonds extending through the second aperture and coupled to the chip contacts of the second microelectronic element, wherein the edge contacts are coupled to the first and second microelectronic elements through the first and second wire bonds.
