Patent ID: 8885380

Claim:
A semiconductor package comprising: a package interface including at least a first pair of terminals, a stack of semiconductor chips; a plurality of stacks of through substrate vias, each stack of through substrate vias comprising plural through substrate vias of respective ones of the semiconductor chips, each through substrate via electrically connected to a through substrate via of an immediately adjacent semiconductor chip; an interface circuit including an input connected to the first pair of terminals to receive a differential signal providing first information, and including an output to provide an output signal including the first information in a single-ended signal format to at least one of the plurality of stacks of through substrate vias; and one or more single terminals included in the package interface, the one or more single terminals connected to an input to receive one or more respective single-ended input signals, wherein the differential signal is a data signal, and the one or more respective single-ended input signals are not data signals.
