Claim 11:
12. A memory array comprising strings of memory cells, comprising:
laterally-spaced memory blocks individually comprising a vertical stack comprising alternating insulative tiers and conductive tiers, operative channel-material strings of memory cells extending through the insulative tiers and the conductive tiers; and
intervening material laterally-between and longitudinally-along immediately-laterally-adjacent of the memory blocks, the intervening material comprising longitudinally-alternating first and second regions individually comprising at least one pillar extending through at least a majority of the insulative tiers and the conductive tiers through which the channel-material strings extend, the at least one first-region pillar or the at least one second-region pillar being wider at its bottom than at its top in a direction of horizontal and longitudinal orientation of the memory blocks.
