Abstract

A three dimensional memory module and system are formed with at least one slave chip stacked over a master chip. Through semiconductor vias (TSVs) are formed through at least one of the master and slave chips. The master chip includes a memory core for increased capacity of the memory module/system. In addition, capacity organizations of the three dimensional memory module/system resulting in efficient wiring is disclosed for forming multiple memory banks, multiple bank groups, and/or multiple ranks of the three dimensional memory module/system.
