Abstract
A memory array comprises laterally-spaced memory blocks individually comprising a vertical stack comprising alternating insulative tiers and conductive tiers. Channel-material strings of memory cells extend through the insulative tiers and the conductive tiers. Dummy pillars extend through the insulative tiers and the conductive tiers. A lowest of the conductive tiers comprises conducting material and dummy-region material that is aside and of different composition from that of the conducting material. The channel-material strings extend through the conducting material of the lowest conductive tier. The dummy pillars extend through the dummy-region material of the lowest conductive tier. Other embodiments, including method, are disclosed.
