ERROR CORRECTION SYSTEM FOR SINGLE-ERROR CORRECTION, RELATED-DOUBLE-ERROR CORRECTION AND UNRELATED-DOUBLE-ERROR DETECTION

摘要

A system for correcting errors in a code word, including means for correcting single errors, means for detecting unrelated double errors and means for correcting related double errors in the code word. The system is particularly applicable to correcting errors in words generated from a memory system in which it is highly probable that if a double error occurs, it will occur in bits which are related to each other.
