Abstract
A digital memory device includes a moveable element that is configured to move between a first stable position and a second stable position, where the moveable element comprises a first conducting area. The digital memory device further includes a second conducting area on the surface of a substrate. At the first stable position of the moveable element, a first gap exists between the first conducting area and the second conducting area. At the second stable position of the moveable element, a second gap that is smaller than the first gap exists between the first conducting area and the second conducting area. In at least the second stable position, an attractive Casimir force between the moveable element and the substrate holds the moveable element in the stable position.
