Abstract
A memory system for a high performance data processing system comprises a plurality of memory modules. In the preferred embodiment, there are 2.sup.N +1 memory modules. In a specific example, there are 65 such modules. When all 65 modules are enabled, a real-to-physical translation unit generates logical module addresses from 0 to 64 using modulo 65 calculations. Once a module failure is detected, the translation unit maps the real addresses to logical module addresses from 0 to 63 by performing modulo 64 calculations. The contiguous set of logical module addresses are then mapped to a set of physical module addresses which do not include the failed module.
