• memory means for holding data values;
• channel data reading means for reading the channel data value from the nonvolatile memory and storing the channel data value in said memory means;
• read channel data comparing means for determining if an input channel data value is stored in said memory means;
• read address search means for accessing said first memory location of said nonvolatile memory to retrieve said channel attendant data address value of said channel attendant data value, if said input channel data value is determined by said read channel data comparing means to be stored in said memory means;
• and
• an attendant data reading part for reading said channel attendant data value in said second memory location of said nonvolatile memory at the channel attendant data address value retrieved by said read address search means.
