Systems and method for data survivability

A method of storing and retrieving data from a protected memory system, said method comprising:

• storing identical copies of a series of data packets in corresponding memory locations in a plurality of memory modules, each memory module separate from at least one other memory module, each memory module storing one or more copies of the series of data packets;
• reading the series of data packets from one of the plurality of memory modules until an error in the data packet is detected;
• reading a data packet from another of the plurality of memory modules that corresponds to the data packet having the detected error;
• and
• outputting the error-free series of data packets.

A flight data recorder comprising:

• a data acquisition unit configured to receive a plurality of data signals and to generate a series of data packets for storage, at least one of the data packets in the series comprising an error-checking portion;
• a crash-protected memory comprising a memory array of a plurality of memory modules each separately located with respect to each other;
• and
• a memory controller communicatively coupled to said data acquisition unit and to each of the plurality of memory modules, said controller configured to:
• store identical copies of the series of data packets in corresponding memory locations in the plurality of memory modules, each memory module separate from at least one other memory module, each memory module storing one or more copies of the series of data packets;
• read the series of data packets from one of the plurality of memory modules until an error in the data packet is detected;
• read a data packet from another of the plurality of memory modules that corresponds to the data packet having the detected error;
• and
• output the error-free series of data packets.
