Electronic device including circuitry comprising open failure-susceptible components, and open failure-actuated anti-fuse pathway

摘要

An electronic device including series-connected open failure-susceptible components and re-routing assemblies for directing current through an ancillary current path to maintain operability of the series array despite an open-failed component therein. The re-routing assembly can be constituted as an ancillary circuit containing a bypass control element arranged to maintain the ancillary circuit in a non-current flow condition when none of the open failure-susceptible components has experienced open failure, and to re-route current from a main circuit around an open-failed component therein and through the ancillary circuit and back to the main circuit, to bypass the open-failed component so that all non-failed series components of the main circuit remain operative when electrically energized.
