PoP also enables a path using standard commodity memory footprints, rather than the
custom designs typically required for SiP implementation ( T
able 2.3 ).
In contrast, PoP testing can be independent of the fi nal SoC solution, so a PoP can use
standard commodity memory design-for-test (DFT) modes. PoP also eliminates the
procurement-related business issues of the SiP package, which is implemented by a logic
chip supplier who must procure the memory chips from another IC supplier.
The single impediment to PoP ’ s proliferating, and taking over the SiP domain, is the lack
of pinout and footprint standards similar ...
