Abstract:
A microelectronic package can include a support element having first and second surfaces and substrate contacts at the first or second surface, zeroth and first stacked microelectronic elements electrically coupled with the substrate contacts, and terminals at the second surface electrically coupled with the microelectronic elements. The second surface can have a southwest region encompassing entire lengths of south and west edges of the second surface and extending in orthogonal directions from the south and west edges one-third of each distance toward north and east edges of the second surface, respectively. The terminals can include first terminals at a southwest region of the second surface, the first terminals configured to carry address information usable by circuitry within the microelectronic package to determine an addressable memory location from among all the available addressable memory locations of the memory storage arrays of at least one of the zeroth or first microelectronic elements.
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.
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.

The microelectronic elements can have a plurality of edges bounding the face, and a plurality of element contacts at the face electrically coupled with the terminals through the contacts of the substrate. Each edge of the microelectronic element can be oriented at an oblique angle with respect to the peripheral edges of the substrate.
Abstract:
An apparatus relates generally to a microelectronic assembly. In this apparatus, a first substrate and a second substrate each have opposing surfaces. Contact arrangements are disposed on a surface of the first substrate, including: first contacts disposed as a ring to provide a first array of the contact arrangements on such surface; and second contacts disposed interior to the ring of the first contacts to provide a second array of the contact arrangements on the first surface. The first contacts and the second contacts are for interconnection with first microelectronic dies and second microelectronic dies. The second microelectronic dies are disposed below the first microelectronic dies in same a package as the first microelectronic dies. The first microelectronic dies and the second microelectronic dies include at least two ranks thereof for commonly sharing the first contacts and the second contacts among the first microelectronic dies and the second microelectronic dies.

Abstract:
In-package fly-by signaling can be provided in a multi-chip microelectronic package having address lines on a package substrate configured to carry address information to a first connection region on the substrate having a first delay from terminals of the package, and the address lines being configured to carry the address information beyond the first connection region to at least to a second connection region having a second delay from the terminals that is greater than the first delay. Address inputs of a first microelectronic element, e.g., semiconductor chip, can be coupled with each of the address lines at the first connection region, and address inputs of a second microelectronic element can be coupled with each of the address lines at the second connection region.

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.
