Abstract
A quasi-volatile memory (QV memory) stack includes at least one semiconductor die, having formed thereon QV memory circuits, bonded to a second semiconductor on which a memory controller for the QV memory ('QV memory controller') is formed. The circuits in the bonded semiconductor dies are electrically connected using numerous copper interconnect conductors and conductive through-silicon vias (TSVs). The QV memory controller may include one or more interfaces to additional devices (“back-channel devices”) to enable the QV memory controller to also serve as a controller for each back-channel device and to provide additional services. The QV memory controller performs data transfers between a back-channel device and the QV memory without intervention by the host CPU.
