Abstract
A nonvolatile semiconductor storage device and method of managing the same are provided. The nonvolatile semiconductor storage device includes a nonvolatile memory configured to be electrically rewritable; and a controller configured to control an access area of the nonvolatile memory on the basis of information associated with management of the nonvolatile memory. The controller partitions an area of the nonvolatile memory for management and numbers management information for managing data for each area and a map of the management information in an integrated manner to write the numbered management information and map to the nonvolatile memory, thereby determining whether the management information and the map are normal on the basis of the numbering.
