Arrangement for the automatic reconfiguration of an intact equipment combination

摘要

An arrangement switches from a defective device of a multi-device system to a redundant duplicate device by assigning a non-volatile memory to each device. Each memory has a single read line to a logic circuit that turns on a device or its duplicate depending upon the memory status. An error detector monitors the devices to activate appropriate memory circuits and logic circuits upon detection of a defect in a particular device.
