Claim 13:
14. 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 memory blocks, the intervening material comprising longitudinally-alternating first and second pillars individually extending through at least a majority of the insulative tiers and the conductive tiers through which the channel-material strings extend, the first pillars individually being wider at their bottoms than at their tops in a direction of horizontal and longitudinal orientation of the memory blocks, the second pillars individually being wider at their tops than at their bottoms in said direction.
