A microelectromechanical device, in particular a non-volatile memory module or a relay, comprising: a mobile body including a top region and a bottom region; top electrodes facing the top region; and bottom electrodes, facing the bottom region. The mobile body is, in a resting condition, at a distance from the electrodes. The latter can be biased for generating a movement of the mobile body for causing a direct contact of the top region with the top electrodes and, in a different operating condition, a direct contact of the bottom region with the bottom electrodes. In the absence of biasing, molecular-attraction forces maintain in stable mutual contact the top region and the top electrodes or, alternatively, the bottom region and the bottom electrodes. 1. A microelectromechanical device , comprising:a mobile body configured to move in a direction, and including a first coupling region and a second coupling region;a first electrode and a second electrode, directly facing the first coupling region and electrically insulated from one another; anda third electrode and a fourth electrode, directly facing the second coupling region and electrically insulated from one another, wherein:said mobile body is, in a resting condition, at a distance from the first and second electrodes and from the third and fourth electrodes,the mobile body, the first and second electrodes, and the third and fourth electrodes are configured to be electrically biased into generating a movement of the mobile body in said direction for causing, in a first operating condition, a direct contact of the first coupling region with the first and second electrodes and, in a second operating condition, a direct contact of the second coupling region with the third and fourth electrodes,the first coupling region and the first and second top electrodes are configured, in the first operating condition and in the absence of electrical biasing, to remain in stable mutual contact as a result of molecular- ...
