Abstract
SEU-hardening series resistances loads are formed within the gate structures of cross-coupled inverters of a latch. For some embodiments, the gate contact for the input of each cross-coupled inverter has a sufficiently high resistance to provide the SEU-hardening series resistance. For other embodiments, a conductive trace layer coupled to the input of each cross-coupled inverter includes a high-resistivity portion that provides the SEU-hardening series resistance.
