Systems and methods for integration of heterogeneous circuit devices

A memory cell uses a pair of cantilevers to store a bit of information. Changing the relative position of the cantilevers determines whether they are electrically conducting or not. The on and off state of this mechanical latch is switched by using, for example, electrostatic, electromagnetic or thermal forces applied sequentially on the two cantilevers to change their relative position. The amount of power required to change the state of the cell is reduced by supporting at least one of the cantilevers with at least one lateral projection that is placed in torsion during cantilever displacement. After a bit of data is written, the cantilevers are locked by mechanical forces inherent in the cantilevers and will not change state unless a sequential electrical writing signal is applied. The sequential nature of the required writing signal makes inadvertent, radiation or noise related data corruption unlikely.
