Abstract
Systematic and noise-induced errors, as detected in words extracted from corresponding locations in a m .times. n word organized memory array, are distinguished as to their source and are corrected by using the conjunction of a nonzero error checking syndrome and the a'priori location defects status as indexed by the location address of the extracted words from an external table memory.
