The concepts of molecular switch, molecular logics and memories are intimately related. In this work a review of these three topics is given. While the main examples concern the field of inorganic chemistry, in a few cases organic systems are presented to better illustrate the concepts. The basic notions of the logics gates usually used by the nowadays computers is presented and the modus operandi to transpose these concepts to the molecular level is discussed. Examples of switches driven by external stimuli such as light-induced, metal-ion, redox, photobistable, and complexation-decomplexation are described in this chapter. The extension of switches working in solution to solid devices are shown in this chapter. The alternative to the current based switches, the quantum-dot cellular automata, based on switches changing by quantum-mechanical tunneling and coulomb interactions is a new paradigm shown in this chapter. Memories in particular optical memories are reported in this chapter.
