Abstract
Apparatuses and methods for interconnections for 3D memory are provided. One example apparatus can include a stack of materials including a plurality of pairs of materials, each pair of materials including a conductive line formed over an insulation material. The stack of materials has a stair step structure formed at one edge extending in a first direction. Each stair step includes one of the pairs of materials. A first interconnection is coupled to the conductive line of a stair step, the first interconnection extending in a second direction substantially perpendicular to a first surface of the stair step.
