    Abstract: According to one embodiment, a memory device includes: a first variable resistance layer; first and second semiconductor layers being in contact with the first variable resistance layer; a first word line; a second word line being adjacent to the first word line; and a third word line being adjacent to the first and second word lines with the first semiconductor layer, the first variable resistance layer, and the second semiconductor layer interposed therebetween, and provided between the first word line and the second word line. In the first variable resistance layer, a first region including a shortest path connecting the first word line and the third word line functions as a first memory cell, and a second region including a shortest path connecting the third word line and the second word line functions as a second memory cell.

    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.
