摘要： A memory system in embodiments includes a nonvolatile semiconductor memory that stores user data, a forward lookup address translation table and a reverse lookup address translation table, and a controller. The controller is configured to determine that the user data stored in the nonvolatile semiconductor memory is valid or invalid based on these two tables. The controller may perform data organizing of selecting data determined valid and rewriting the data in a new block. The controller may perform write processing and rewriting processing to the new block alternately at a predetermined ratio. The controller may determine whether a predetermined condition is satisfied on a basis of addresses included in write requests and write data in the MLC mode when the condition is satisfied and write data in the SLC mode when the condition is not satisfied.

摘要： Provided are a process and an apparatus for producing gypsum boards, both of which feature minimized occurrence of defective products and especially excellent continuous productivity and superb efficiency. Making use of the facts that lining paper sheets for gypsum boards are insulators and a gypsum slurry held between the lining paper sheets is a good electrical conductor, a detection of an electric current flowing between an upper forming unit and a lower forming unit or a like method makes it possible to promptly detect any localized tearing which may occur in the overlay paper and/or underlay paper due to an undesired object or the like mixed in during continuous production of gypsum boards and moreover, to readily remove the undesired object or the like as a cause for the tearing without stopping the production of gypsum boards while preventing the localized tearing from spreading over the entire width of the paper. The production process and apparatus, therefore, permit stable and continuous production of gypsum boards.

摘要： A memory system comprising a volatile memory unit, a nonvolatile memory unit, and a controller that performs data transfer between a host system and the nonvolatile memory unit via the volatile memory unit stores management information including a storage position of the data stored in the nonvolatile memory unit during a startup operation into the volatile memory unit, and performs, while updating stored management information, data management in the volatile and nonvolatile memory units based on the stored management information. The nonvolatile memory unit includes a snapshot storing area storing a snapshot which is the management information stored in the volatile memory unit at a certain point, a main log storing area storing a main log which is an update information of the management information stored in the volatile memory unit, and a backup log storing area storing a backup log having contents same as contents of the main log. The controller stores the management information of the volatile memory unit in the snapshot storing area as a snapshot when a predetermined condition is satisfied, and sequentially stores the main log in the main log storing area when the management information is changed and the backup log in the backup log storing area.
