Memory controller utilizing an error coding dispersal function

A memory controller comprises:

• an interface for coupling to a memory device;
• and
• a processing module operably coupled to the interface, wherein the processing module is configured to function as a memory controller processing module and a distributed storage processing module, wherein:
• the memory control processing module is operable to receive a data segment memory transfer request from a first memory layer to a second memory layer;
• the memory control processing module is operable to determine whether the data segment is stored within the first memory layer in accordance with an error coding dispersal function;
• when the data segment is stored in accordance with the error coding dispersal function, the memory control processing module is operable to determine whether the data segment is to be stored in the second memory layer in accordance with the error coding dispersal function;
• when the data segment is not to be stored in the second memory layer in accordance with the error coding dispersal function, the dispersed storage processing module is operable to:
• retrieve a plurality of data slices from the first memory layer;
• convert the plurality of data slices into a reconstructed data segment;
• determine whether to store the reconstructed data segment in accordance with a second error coding dispersal function in the second memory layer;
• when the reconstructed data segment is to be stored in accordance with the second error coding dispersal function, perform the second error coding dispersal function on the reconstructed data segment to produce a second plurality of data slices;
• and
• send the second plurality of data slices to the second memory layer.
