Abstract

A computing system comprises at least a processing module, a main memory, a memory controller, and a plurality of memory components. A method begins by the memory controller receiving a memory access request regarding a data segment. The method continues with the memory controller interpreting the memory access request to determine whether an error encoding dispersal function of the data segment is applicable. The method continues with the memory controller identifying at least a threshold number of memories based on the memory access request, wherein the threshold number of memories includes at least one of the main memory and/or one or more of the plurality of memory components, when the error encoding dispersal function is applicable. The method continues with the memory controller addressing the at least a threshold number of memories to facilitate the memory access request.

First claim

What is claimed is:

1. A memory controller comprises:
an input unit operable to receive a read request regarding a data segment; and
a processing unit operable to:
interpret the read request to determine whether the data segment is encoded using an error encoding dispersal function and stored as a set of encoded data slices;
when the data segment is stored as the set of encoded data slices:
identify one or more memories that are storing at least a threshold number of encoded…
