Ser tolerant flip flop having a redundant latch

摘要

A circuit configured to resist a radiation strike includes a latch having an input node and an output node, and a first resistive element configured to be coupled to the first input node to resist a change of a state data at the input node from a radiation strike. The circuit further includes an input stage coupled to the input node and configured to be clocked to transfer the state data to the latch. The circuit further includes a pass circuit configured to be clocked after the input stage to couple the first resistive element to the input node after the input stage transfers the state data to the latch.
