Abstract:
An apparatus relating generally to a substrate is disclosed. In such an apparatus, the substrate has a first surface and a second surface opposite the first surface. The first surface and the second surface define a thickness of the substrate. A via structure extends from the first surface of the substrate to the second surface of the substrate. The via structure has a first terminal at or proximate to the first surface and a second terminal at or proximate to the second surface provided by a conductive member of the via structure extending from the first terminal to the second terminal. A barrier layer of the via structure is disposed between at least a portion of the conductive member and the substrate. The barrier layer has a conductivity configured to offset a capacitance between the conductive member and the substrate when a signal is passed through the conductive member of the via structure.

An apparatus for reducing load in a memory module. In such an apparatus, there is a circuit platform with a plurality of memory chips coupled to the 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:
A microelectronic package can include a substrate and a microelectronic element. The substrate can include terminals comprising at least first power terminals and other terminals in an area array at a surface of the substrate. The substrate can also include a power plane element electrically coupled to the first power terminals. The area array can have a peripheral edge and a continuous gap between the terminals extending inwardly from the peripheral edge in a direction parallel to the surface. The terminals on opposite sides of the gap can be spaced from one another by at least 1.5 times a minimum pitch of the terminals. The power plane element can extend within the gap from at least the peripheral edge at least to the first power terminals. Each first power terminal can be separated from the peripheral edge by two or more of the other terminals.
