Abstract

A memory device includes a grounded molding. The memory device includes a substrate having a first surface for a memory die, where the substrate has ground vias through substrate to connect to a ground reference. The substrate has a ball grid array (BGA) on the opposite surface, including perimeter balls to connect to ground connections. The grounded molding includes an electrically conductive epoxy mold to cover the memory die, where the electrical conductivity of the molding, with the molding grounded can provide radio frequency interference (RFI) shielding.
