Stub minimization using duplicate sets of signal terminals

摘要

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.

1. A microelectronic structure, comprising:
active elements defining a memory storage array; address input contacts for receipt of address information specifying locations within the storage array; and data contacts configured for transferring data at least one of from the storage array or to the storage array, the structure having a first surface and first and second peripheral edges each extending away from the first surface and being opposite from one another, and the structure having terminals exposed at the first surface, the terminals including first terminals and the structure being configured to provide address information received at the first terminals to the address input contacts, each of at least some of the first terminals having a signal assignment including information to be transferred to one or more of the address input contacts, the first terminals including first and second duplicate sets thereof disposed on first and second opposite sides, respectively, of a theoretical plane normal to the first surface, wherein signal assignments of the first terminals disposed on the first side are symmetric about the theoretical plane with the signal assignments of the first terminals disposed on the second side, the terminals further including first and second duplicate sets of second terminals coupled with the data contacts and exposed at the first surface, wherein the first set of the first terminals are disposed between the first set of the second terminals and the first peripheral edge, and the second set of the first terminals are disposed between the second set of the second terminals and the second peripheral edge.
