Strings of series-coupled memory cells selectively coupled to the same bit line may facilitate increased memory densities, reduced fabrication steps and faster read operations when compared to traditional memory array architectures. An evacuation system is connected to a plurality of chambers. The second electrode is elevationally outward of the first electrode. The improvements also make better use of the storage devices involved in the data backup process. The lower portion of the main body is shaped for easy grasping by infants and toddlers.
