Abstract: A storage device includes a memory array and a memory controller. The memory controller generates read and write commands for the memory array. An error correction code engine for the storage device is operable to use a plurality of different codeword sizes, different code rates, or different ECC algorithms. Logic is included that applies a selected codeword size, code rate or ECC algorithm in dependence on the operating conditions of the memory array.

Abstract: Systems, methods, and apparatus including computer-readable mediums for managing memories by overlapping ranges of pages in nonvolatile memory systems are provided. An example memory system includes a memory controller coupled to a memory and configured to: determine a range of logical addresses associated with a command, search particular mapping tables including the range of logical addresses in mapping pages in the memory, determine whether a starting address of the range of logical addresses is in an overlapped range of first and second sequential mapping pages, the overlapped range including logical addresses of one or more mapping tables duplicated in the first and second mapping pages, determine which of the first and second mapping pages from which the particular mapping tables to be loaded based on a result of determining whether the starting address is in the overlapped range, and load the particular mapping tables from the determined mapping page.
