Abstract: Methods, systems, and devices for a capacitive pillar architecture for a memory array are described. An access line within a memory array may be, include, or be coupled with a pillar. The pillar may include an exterior electrode, such as a hollow exterior electrode, surrounding an inner dielectric material that may further surround an interior, core electrode. The interior electrode may be maintained at a voltage level during at least a portion of an access operation for a memory cell coupled with the pillar. Such a pillar structure may increase a capacitance of the pillar, for example, based on a capacitive coupling between the interior and exterior electrodes. The increased capacitance may provide benefits associated with operating the memory array, such as increased memory cell programming speed, programming reliability, and read disturb immunity.
