Abstract
A method and system for protecting erroneous data from being stored in a memory, such DATA comprising a series of data words terminating in a Cyclic Redundancy Check (CRC). The method includes: checking the CRC of the data words while delaying the DATA from passing to an output; corrupting the delayed data words if such checking determines a CRC error, such corruption of one of the data words being performed prior to the data words pass to said output; detecting whether such data word at the output is corrupt; and inhibiting storage of such data words in the memory if such one of the data words at the output is detected as being corrupt.
