Abstract
Some embodiments include an assembly having a memory stack which includes dielectric levels and conductive levels. A select gate structure is over the memory stack. A trench extends through the select gate structure. The trench has a first side and an opposing second side, along a cross-section. The trench splits the select gate structure into a first select gate configuration and a second select gate configuration. A void is within the trench and is laterally between the first and second select gate configurations. Channel material pillars extend through the memory stack. Memory cells are along the channel material pillars.
