US Patent 7515454 CBRAM cell and CBRAM array, and method of operating thereof

According to one embodiment of the present invention, a CBRAM cell includes a solid electrolyte block having at least three solid electrolyte contacting areas, electrodes electrically connected to the solid electrolyte contacting areas, wherein conductive paths are formable, erasable or detectable within the solid electrolyte block by applying voltages between the solid electrolyte contacting areas using the electrodes as voltage suppliers, and wherein the contacting areas are spatially separated from each other such that conductive paths starting from different solid electrolyte contacting areas or ending at different solid electrolyte contacting areas do not overlap each other.
