Abstract
A fault tolerant addressing arrangement for a solid-state disk comprising partially defective memory devices is provided. The addressing technique increments both row and column addresses when establishing locations for the storage of symbols so that the same rows and columns are not addressed for any two symbols. The technique also complements certain portions of the symbols' address to ensure addressing of different locations within each memory device.
