Zusammenfassung:Apparatus for determining the field position (00, 01, 10, 11) of an integrated circuit (18) within a reticle area (12) which contains a plurality of such integrated circuits (14-20) includes a plurality of memory cells (76, 80) formed within the integrated circuit (18) for encoding the field position. Circuitry (40, 94, 100, 104, 106) is provided for reading the states of the memory cells to ascertain the field position.
