摘要： PROBLEM TO BE SOLVED: To provide a logic latch for storing output data, in addition to reinforcing of the radioactivity resistance. SOLUTION: A decision block is incorporated into a circuit design to provide reinforcement against single event upset and to store data. The decision block includes a storage element that stores data as long as inputs to the decision block remain constant. The decision block receives a first data input and a second data input from redundant logic blocks or from logic blocks, designed to provide complementary outputs. The decision block provides an output that is at a same logic level as the first data input, when the two data inputs are at expected logic levels during normal operating conditions (that is, there is no disturbances). The decision block provides an output that is at the same logic level as that of the previous output of the decision block, when the two data inputs are not at expected logic levels during normal operating conditions.
