  • Patent number: 8095856
    Abstract: A system and method corrects erroneous sections received in a memory by pre-filling at least a portion of memory with a pre-defined value. If a received data packet is valid, the valid received data packet is stored over the pre-defined values in the memory location associated with the valid data packet. Values associated with a data segment and an adjacent data segment in the memory are compared to the pre-defined value. When the values of each data segment match the pre-defined values, then each data segment is an erroneous data segment.
