    Abstract: A method for reducing load in a memory module. In such a method, a plurality of memory chips are coupled to a circuit platform. Each memory chip of the plurality of memory chips each has a plurality of memory dies. At least one controller is coupled to the circuit platform and further coupled to the plurality of memory chips for communication with the plurality of memory dies thereof. The at least one controller is for receiving chip select signals to provide a plurality of rank select signals in excess of the chip select signals. The plurality of memory dies are coupled with wire bonds within the plurality of memory chips for a reduced load for coupling the circuit platform for communicating via a memory channel. The load is sufficiently reduced for having at least two instances of the memory module share the memory channel.

    Abstract: Vertical memory modules enabled by fan-out redistribution layer(s) (RDLs) are provided. Memory dies may be stacked with each die having a signal pad directed to a sidewall of the die. A redistribution layer (RDL) is built on sidewalls of the stacked dies and coupled with the signal pads. The RDL may fan-out to UBM and solder balls, for example. An alternative process reconstitutes dies on a carrier with a first RDL on a front side of the dies. The dies and first RDL are encapsulated, and the modules vertically disposed for a second reconstitution on a second carrier. A second RDL is applied to exposed contacts of the vertically disposed modules and first RDLs. The vertical modules and second RDL are encapsulated in turn with a second mold material. The assembly may be singulated into individual memory modules, each with a fan-out RDL on the sidewalls of the vertically disposed dies.

    Abstract: A microelectronic package has terminals at a surface of a substrate having first and second half areas, each half area extending from a diagonal that bisects the first surface and a respective opposite corner of the first surface. Terminals for carrying data and address information in the first half area provide first memory channel access to a first memory storage array, and terminals for carrying data and address information in the second half area provide second memory channel access to a second memory storage array. The package may include first and second microelectronic elements overlying a same surface of the substrate which may be stacked in transverse orientations.
