Abstract
In a semiconductor device, a first stack is positioned over substrate and includes a first pair of transistors and a second pair of transistors stacked over the substrate. A second stack is positioned over the substrate and adjacent to the first stack. The second stack includes a third pair of transistors and a fourth pair of transistors stacked over the substrate. A first capacitor is stacked with the first and second stacks. A second capacitor is positioned adjacent to the first capacitor and stacked with the first and second stacks. A first group of the transistors in the first and second stacks is coupled to each other to form a static random-access memory cell. A second group of the transistors in the first and second stacks is coupled to the first and second capacitors to form a first dynamic random-access memory (DRAM) cell and a second DRAM cell.
