Patent ID: 7131042

Claim:
A method of testing a device configuration having an external data port and at least one internal data port, wherein each data port comprises multiple pads, and wherein the pads of the external and internal data ports support simultaneous bi-directional (SBD) data signaling, the method comprising: connecting the pads of the external data port to communicate with a tester using unidirectional data signaling; connecting at least one first internal data port pad to a second internal data port pad; and setting internal data paths in at least one device of the device configuration to concurrently: route a first write signal received on a first external data port pad to an output driver of the first internal data port pad, route a second write signal received on a second external data port pad to an output driver of the second internal data port pad, route a signal received by a receiver of the first internal data port pad to a third external data port pad as a first read signal, and route a signal received by a receiver of the second internal data port pad to a fourth external data port pad as a second read signal.
