Abstract:
A semiconductor package is discussed having a single CE signal during electrical test and a plurality of CE signals during normal operation thereafter. After electrical testing of the memory die during fabrication, the electrical traces carrying the single CE signal from the memory test pad matrix to each of the memory die may be severed. Severing the electrical traces from the memory test pad matrix electrically isolates the multiple electrical traces between the controller die and memory die, and allows separate and individual CE signals between the controller die and memory die during normal usage of the memory die.

Abstract:
A system of micro balls is disclosed for coupling an electronic component to a printed circuit board. The micro balls have a small diameter, and each contact pad may include an array of two or more micro balls. An example of a micro ball may include a polymer core, surrounded by a copper layer, which is in turn surrounded by a layer of solder.

A signal carrier medium is disclosed including support vias for maintaining laminated portions of the signal carrier medium together. The signal carrier medium includes metal portions such as a contact pad. The metal portions may have one or more adjacent support vias for dissipating stresses which build in the metal portions.

International Classification:
H05K 1/11 H05K 1/18
Abstract:
A semiconductor package such as a multi-chip package is disclosed. The semiconductor package may be configured for dual second level interconnection onto a printed circuit board of a host device. Thus, a single semiconductor package may be used on host printed circuit boards having different configurations.
