  • Patent number: 7719304
    Abstract: The present invention provides a radiation hardened flip-flop formed from a modified temporal latch and a modified dual interlocked storage cell (DICE) latch. The temporal latch is configured as the master latch and provides four output storage nodes, which represent outputs of the temporal latch. The DICE latch is configured as the slave latch and is made of two cross-coupled inverter latches, which together provide four DICE storage nodes. The four outputs of the temporal latch are used to write the four DICE storage nodes of the DICE latch. The temporal latch includes at least one feedback path that includes a delay element, which provides a delay.
