摘要:Disclosed is a package-on-package (PoP) assembly comprises a two-tieredwindowed ball grid array (BGA) and a system on a chip (SoC) package. Window openings inthe two tiers of the BGA are of different sizes to allow for wirebond landing pads on the
first tier. A DRAM die is mounted to the BGA flipped over (i.e., wirebond pads facing theBGA package.) The DRAM die is wirebonded through the window in the BGA. For multi-channel systems and higher memory capacity, the DRAM die will have low-cost through-silicon vias (TSVs) that connect to stacked DRAM die(s). The stacked DRAM dies may beoffset or rotated to align active TSVs with passive TSVs thereby enabling uniqueconnections to certain DRAM dies in the stack.
