Abstract
A memory system for a digital computer has first and second memory modules having differing numbers of independently-accessible banks and unlike capacities. The digital computer also has an addressing arrangement that employs horizontal stacking for interleaving together the banks of both the first and second memory modules, such that the first memory module is interleaved to a first level and the second memory module to a second, different level. The invention also embraces a method of interleaving the memory system employing horizontal stacking. In usual applications, horizontal stacking permits the memory system to be interleaved to a higher level than that achieved by conventional vertical stacking schemes.
