Zusammenfassung:Various embodiments comprise apparatuses and methods, such as a memory stack having a continuous cell pillar. In various embodiments, the apparatus includes a source material, a buffer material, a select gate drain (SGD), and a memory stack arranged between the source material and the SGD. The memory stack comprises alternating levels of conductor materials and dielectric materials. A continuous channel-fill material forms a cell pillar that is continuous from the source material to at least a level corresponding to the SGD.
