Abstract
A static RAM cell may be formed on the basis of two double channel transistors and a select transistor, wherein a body contact may be positioned laterally between the two double channel transistors in the form of a dummy gate electrode structure, while a further rectangular contact may connect the gate electrodes, the source regions and the body contact, thereby establishing a conductive path to the body regions of the transistors. Hence, compared to conventional body contacts, a very space-efficient configuration may be established so that bit density in static RAM cells may be significantly increased.
