A multi-chip memory module may be formed including two or more stacked
integrated circuits mounted to a substrate or lead frame structure. The
memory module may include means to couple one or more of the stacked
integrated circuits to edge conductors in a memory card package
configuration. Such means may include the capability to utilize bonding
pads on all four sides of an integrated circuit. A lead frame structure
may be divided into first and second portions. The first portion may be
adapted to receive the stacked integrated circuits and the second portion
may include a plurality of conductors. The first portion may also be
adapted to couple at least one of the integrated circuits to power and
ground conductors on the second portion. In one embodiment, the first
portion may include the lead frame paddle and a conductive ring. In
another embodiment, the first portion may include first and second
coplanar elements.
