Abstract
Ladder network comprises control terminals including at least ground terminal and master terminal, and slave terminals, each individually connected to ground terminal through fuse elements, respectively. The slave terminals are also sequentially linked, each to the next through antifuses, respectively. Master terminal is connected to slave terminal. By applying programming signals to control terminals, master terminal may be disconnected from ground terminal and sequentially connected to each slave terminal. Described ladder variations include segmented ladder, wherein master terminal can be sequentially connected to, and subsequently disconnected from, second conductors; hierarchical ladder network; and programmable SAW transducer. Finally, a programmable architecture based upon such ladder networks, suitable for incorporation within a configurable IC package, is described, including also a programmable contact structure if the package is stackable.
