The three-dimensional memory can be used to carry the test data andor test-data seeds for the circuit-under-test. A permeable zone having a first patterned web of channels radiating outwardly from the outlet of the injection well and connecting to a second patterned web of channels radiating outwardly from the inlet of the production well is formed in the reservoir. A third area diameter of the third area is larger than the second area diameter of the second area.
