Cipurile de memorie dintr-o stivă sunt conectate prin tehnologia TSV (<a href="/w/index.php?title=Through-Silicon_Via&action=edit&redlink=1" class="new" title="Through-Silicon Via — pagină inexistentă">Through-Silicon Via</a>).

Stivuirea 3DS pe verticală utilizează mai bine spațiul disponibil pe DIMM-uri. Prin această tehnologie sunt posibile capacități de 128 GB, 256 GB și 512 GB pe un singur DIMM.
