ABSTRACT:
A cross-coupled checking circuit is disclosed in which two identical integrated circuit chips are configured in a complementary manner and connected in parallel to the same inputs and outputs. One chip drives the data output data and the other chip drives the check symbol output corresponding to the output data. Each chip generates internal results and compares them to the output driven by the other chip.
