Abstract

An electronic device comprises a stack comprising tiers of alternating conductive levels and insulative levels overlying a source, slots extending vertically through the stack and dividing the stack into blocks, and support pillars within the slots and extending vertically through the stack. The support pillars exhibit a lateral dimension in a first horizontal direction relatively larger than a lateral dimension of the slots in the first horizontal direction, substantially orthogonal to a second horizontal direction in which the slots extend. Related memory devices, systems, and methods are also described.
