MEMORY FAULT CORRECTION SYSTEM

摘要

A memory system is disclosed which is internally self-correcting when a memory failure occurs. Upon detection of a memory output error, the bit which is incorrect is automatically identified and the output from the memory column which provided the error bit is inhibited. At the same time, a spare memory column is activated and the information which was initially in the error column is transferred to the now activated spare column. The output of the spare column is then directed into the bit location of the inhibited column.
