Abstract
An integrated circuit (IC) device implemented according to an architectural design that specifies that the IC device is required to have one functional module, to perform a first function, connected to another functional module, to perform a second function. The IC device includes a first IC chip having a plurality of first functional modules implemented thereon. Some of the first functional modules are defective and others of the first functional modules are non-defective. At least one of the non-defective first functional modules is operable to perform the first function. The IC device also includes a second IC chip having a plurality of second functional modules implemented thereon. Some of the second functional modules are defective and others of the second functional modules are non-defective. At least one of the non-defective second functional modules is operable to perform the second function. The IC device further includes a bus, a first tri-state gate to electrically connect the non-defective first functional module to the bus, and the second tri-state gate to electrically connect the non-defective second functional modules to the bus.
