Abstract
A memory array comprising strings of memory cells comprises laterally-spaced memory blocks individually comprising a vertical stack comprising alternating insulative tiers and conductive tiers above a conductor tier. Strings of memory cells comprise channel-material-string constructions that extend through the insulative tiers and the conductive tiers into the conductor tier. The channel material of the channel-material-string constructions directly electrically couples to conductor material of the conductor tier. The conductor tier comprises islands comprising material of different composition from that of the conductor material of the conductor tier that surrounds individual of the islands. The islands are directly against bottoms of the channel-material-string constructions. Intervening material is laterally-between and longitudinally-along immediately-laterally-adjacent of the memory blocks. Other aspects, including method, are disclosed.
