The figure illustrates a technique for isolating failing memory modules in a working system. As part of the manufacturing process, processors are tested, and although memory errors usually won't stop the processor, it is desirable to fix any memory errors when found. Isolating memory modules permits Manufacturing the ability to replace defective main storage modules by using only the processor itself and not an additional card tester. It is not always possible to use a card tester on the memory cards.
