A memory network includes a plurality of memory nodes each identifiable by an ordinal number m, and a set of links divided into N subsets of links, where each subset of links is identifiable by an ordinal number n. For each subset of the plurality of N subsets of links, each link in the subset connects two memory nodes that have ordinal numbers m differing by b(n-1), where b is a positive number. Each of the memory nodes is communicatively coupled to a processor via at least two non-overlapping pathways through the plurality of links.
