A system and method for restoring an operating N module redundant NMR) processors when one or more processors is in an out-of-service state. This NMR system comprises N processors each having an individual memory system. An interconnection network is configured to receive data from all N processors, and N voters are connected between the interconnection network and each of the N processors to receive data from the interconnection network and vote on data destined for the N processors. Writes of data from the active processors are rerouted to the interconnection network. Advantageously, there are registers in the interconnection network corresponding to each processor. These registers receive the data from their corresponding processors, and then send the data to all of the voters. The data is voted on and sent to all N processors. Thus, the memories of the out-of-service processors are restored with the active processors while the active processors continue to operate.
