Abstract
In some embodiments, a memory array comprising strings of memory cells comprise laterally-spaced memory blocks individually comprising a vertical stack comprising alternating insulative tiers and conductive tiers. Operative channel-material strings of memory cells extend through the insulative tiers and the conductive tiers. Insulative pillars are laterally-between and longitudinally-along immediately-laterally-adjacent of the memory blocks. The pillars comprise vertically-spaced and radially-projecting insulative rings in the conductive tiers as compared to the insulative tiers. Other embodiments, including methods, are disclosed.
