Abstract:
A microelectronic assembly (300) or system (1500) includes at least one microelectronic package (100) having a microelectronic element (130) mounted face up above a first surface (108) of a substrate (102), one or more columns (138, 140) of contacts (132) extending in a first direction (142) along the microelectronic element front face. Columns (104A, 105B, 107A, 107B) of terminals (105 107) exposed at a second surface (110) of the substrate extend in the first direction. First terminals (105) exposed at surface (110) in a central region (112) thereof having width (152) not more than three and one-half times a minimum pitch (150) of the columns of terminals can be configured to carry address information usable to determine an addressable memory location. An axial plane of the microelectronic element can intersect the central region.
Abstract:
A microelectronic assembly can include a microelectronic package connected with a circuit panel. The package has a microelectronic element having a front face facing away from a substrate of the package, and electrically connected with the substrate through conductive structure extending above the front face. First terminals provided in first and second parallel grids or in first and second individual columns can be configured to carry address information usable to determine an addressable memory location from among all the available addressable memory locations of the memory storage array. The first terminals in the first grid can have signal assignments which are a mirror image of the signal assignments of the first terminals in the second grid.

Abstract:
A microelectronic assembly can include a circuit panel having first and second panel contacts at respective first and second surfaces thereof, and first and second microelectronic packages each having terminals mounted to the respective panel contacts. Each package can include a microelectronic element having a face and contacts thereon, a substrate having first and second surfaces, and terminals on the second surface configured for connecting the package with an external component. The terminals can include first terminals at positions within first and second parallel grids. The first terminals can be configured to carry address information usable by circuitry within the package to determine an addressable memory location from among all the available addressable memory locations of a memory storage array within the microelectronic element. Signal assignments of the first terminals in the first grid can be a mirror image of signal assignments of the first terminals in the second grid.
Abstract:
A microelectronic structure has active elements defining a storage array, and address inputs for receipt of address information specifying locations within the storage array. The structure has a first surface and can have terminals exposed at the first surface. The terminals may include first terminals and the structure may be configured to transfer address information received at the first terminals to the address inputs. Each first terminal can have a signal assignment which includes one or more of the address inputs. The first terminals are disposed on first and second opposite sides of a theoretical plane normal to the first surface, wherein the signal assignments of the first terminals disposed on the first side are a mirror image of the signal assignments of the first terminals disposed on the second side of the theoretical plane.
