1. An electrically actuated switch having a configurable ON/OFF polarity comprising a first electrode; a second electrode; an active region disposed therebetween, said active region comprising a first primary active region and a second primary active region, each comprising at least one material for transporting and hosting ions that act as dopants to control the flow of electrons through the switch, and a secondary active region disposed between said first primary active region and said second primary active region and comprising at least one material for providing a source/sink of ionic dopants for said primary active regions; the switch capable of being configured into a given state by initially causing said dopants to drift toward either of said first electrode or said second electrode to set an initial ON/OFF polarity of said switch.
