Patent ID: 8502390

Claim:
A microelectronic package, comprising: a substrate having first and second oppositely facing surfaces and a plurality of terminals exposed at the first surface, the terminals being configured for connecting the microelectronic package to at least one component external to the package; first and second microelectronic elements each having a face facing the second surface of the substrate; connections electrically coupling the terminals of the package with the first and second microelectronic elements, the connections including groups of connections for carrying respective signals, each group including a first connection extending from a respective terminal of the package to a corresponding contact on the first microelectronic element and a second connection extending from the respective terminal to a corresponding contact on the second microelectronic element, the first and second connections being configured such that a respective signal carried by the first and second connections in each group is subject to propagation delay of the same duration between the respective terminal and each of the corresponding contacts coupled thereto, wherein the signals include a plurality of address signals and a sampling signal usable to sample the address signals.
