Abstract
A nonvolatile memory system includes a nonvolatile memory and a controller. The controller is configured to manage the nonvolatile memory based on management information. The management information of the controller includes a basic table for collectively managing a plurality of blocks and differential information between the blocks. The controller is operable to manage the blocks collectively with the basic table and manage different portions of the blocks within the collected range using the differential information.
