This logical-to-physical mapping for erase blocks is beneficial because if one erase block becomes damaged or inaccessible, the mapping can be changed to map to another erase block. This mitigates the loss of losing an entire virtual erase block when one element's erase block is faulty. The remapping module 430 changes a mapping of a logical address of an erase block to one or more physical addresses of a virtual erase block (spread over the array of storage elements). For example, virtual erase block 1 may be mapped to erase block 1 of storage element SSS 0.0216a, to erase block 1 of storage element SSS1.0216b, . . . , and to storage element M.0216m, virtual erase block 2 may be mapped to erase block 2 of storage element SSS 0.1218a, to erase block 2 of storage element SSS 1.1218b, . . . , and to storage element M.1218m, etc.
