Abstract
A soft error recoverable storage element suitable for use in latches, flip-flops, static ram memory cells and microprocessor pipeline stages. The storage element employs a redundant copy of the stored data value and a feedback loop. One embodiment employs an interlocking four inverter loop with gating devices that blocks the propagation of a soft error induced change of state and causes the storage element to recover its original stored data state.
