The invention encompasses DRAM constructions, capacitor constructions, integrated circuitry, and methods of forming DRAM constructions, integrated circuitry and capacitor constructions. The invention encompasses a method of forming a capacitor wherein: a) a first layer is formed; b) a semiconductive material masking layer is formed over the first layer; c) an opening is etched through the masking layer and first layer to a node; d) a storage node layer is formed within the opening and in electrical connection with the masking layer; e) a capacitor storage node is formed from the masking layer and the storage node layer; and f) a capacitor dielectric layer and outer capacitor plate are formed operatively proximate the capacitor storage node. The invention also includes a DRAM cell comprising: a) a bitline node and a capacitor node electrically connected together through a transistor gate; b) a capacitor electrically connected to the capacitor node, the capacitor comprising; i) a storage node, the storage node in lateral cross-section comprising an outer surface extending over a top of the storage node, along a pair of opposing lateral surfaces of the storage node, and within laterally opposing cavities beneath the storage node; ii) a dielectric layer against the storage node outer surface and extending within the opposing cavities beneath the storage node; and iii) a cell plate layer against the dielectric layer and extending within the opposing cavities beneath the storage node; and c) a bitline electrically connected to the bitline node.
