A dymanic random access memory device is constructed in which a first layer of semiconductive material is used to form series of transistors, using buried contacts on a silicon substrate. A dielectric is formed over the surface, and memory cells include a second layer of semiconductive material which is deposited over a dielectric. The active regions of the DRAM form a "dogbone" pattern, in which active regions exhibit elongate shapes in which each end of the elongate shape is wider than a center leg, and adjacent "dogbone" shapes are nested to form a compact pattern.
