Claim 18:
19. A microelectronic device, comprising:
a stack structure comprising insulative structures vertically interleaved with conductive structures and arranged in tiers;
a series of stadiums in the stack structure, at least one of the stadiums having steps at least partially defined by the conductive structures of a first group of the tiers, and at least one other of the stadiums having additional steps at least partially defined by the conductive structures of a second group of the tiers, the first group of the tiers being at elevations lower than elevations of the second group of the tiers; and
conductive contacts within horizontal areas of stadiums of the series of stadiums, the conductive contacts comprising:
pairs of the conductive contacts, each of the pairs of the conductive contacts extending to a different one of the conductive structures of the first group of the tiers than each other of the pairs of the conductive contacts; and
ones of the conductive contacts each extending to a different one of the conductive structures of the second group of the tiers than each other of the ones of the conductive contacts.
