  • Patent number: 4310901
    Abstract: In a large scale addressable memory which is addressed with an applied block and word address, an auxiliary memory stores word addresses of defective locations within each block of the main memory. Such defective location addresses are supplied by the auxiliary memory in response to the applied block address. A set of comparators compare the applied word address and the defective location word addresses and signal any match. The auxiliary memory also provides a substitute location address for each stored defective location address. When a match is found by a comparator, the corresponding substitute location address is provided to the main memory to access a substitute memory location, which is known to be good.
