Abstract
There is disclosed herein a fault-tolerant memory organization which permits through the incorporation of redundancy the utilization of circuit chips having defective sections. The apparatus involves the use of redundant sections fabricated on the chip in conjunction with a data relocation technique. The relocation scheme utilizes a code-decode arrangement which inserts zeros into the data stream to avoid the defective sections and provides a zero delete arrangement when the previously coded information is retrieved.
