摘要： A right information encryption module 110a comprises a key generation part 111a, a right information encryption part 112a, and a key management information generation part 113a. Key information Km and key management information Mm corresponding to right information are generated and then recorded into a secret recording module 130a. In addition, the right information is encrypted, and then the encrypted right information Enc_a (ROm, Km) and the key management information Mm are recorded into a recording module 140a. This can eliminate the possibility of a capability shortage of a secret area caused by an increase in the data size of the right information including the key information and use restriction information for a content.

摘要： A method for use in a nonvolatile storage device that can resize one or more partitions prevents an address management table from becoming complicated after repeated resizing of partitions. When a partition is resized, a logical-to-physical conversion table is updated by shifting a physical block address corresponding to a partition subsequent to the resized partition by the resized amount of the partition. The method enables both logical addresses corresponding to partitions and logical addresses not corresponding to partitions to be constantly continuous to one another.
摘要翻译：一种用于非易失性存储装置的方法，其可以调整一个或多个分区的大小，防止在重新调整分区大小之后地址管理表变得复杂。当分区被调整大小时，通过将与调整大小的分区之后的分区相对应的物理块地址移位分区的调整大小来更新逻辑到物理转换表。该方法使得与分区对应的逻辑地址和不对应于分区的逻辑地址彼此不断连续。

摘要： A digital still camera performs temporary high-speed writing when capturing a large number of images in a short time. Lengthy processing for erased block allocation or copying performed inside a nonvolatile storage device may disable the captured images to be written completely (may cause some frames to drop). A nonvolatile storage system includes an access device (1001) and a nonvolatile storage device (1002). A button operation of a user on the access device (1001) causes the mode of data writing to the nonvolatile storage device (1002) to be switched. Temporary high-speed writing is performed into a physical block of a nonvolatile memory (27) from which a plurality of data pieces with different logical addresses and different data sizes have been erased. After the temporary high-speed writing, the written data is relocated into a user storage area (272), and an erased block is newly allocated for subsequent temporary high-speed data writing.

摘要： A non-volatile storage device comprises non-volatile memories for storing data; and a memory controller for carrying out control of the non-volatile memory. The memory controller stores second error correcting code as well as first error correcting code stored in the same page of the data. The memory controller, when writing data smaller than a predefined size, does not add the second error correcting code, and stores duplexed data of the data and the first correcting code in a different page. The memory controller, when reading, corrects data using the first and/or second correcting code. The valid data management table manages which logical block stores valid data with respect to an identical logical address.

摘要： The nonvolatile memory device prevents data writing from temporarily slowing down significantly in the middle of writing data to a block when an access device writes all the data in the block in units of a smaller size than the block. The nonvolatile memory device comprises a memory controller including an interface unit configured to receive a first command that identifies a first write range for writing data, and a second command that identifies a second write range that is a part of the first write range and orders to write data to the second write range, an address management unit configured to determine, before data is written into a nonvolatile memory, a new block for writing data to the first write range based on the first command, and a read/write control unit configured to write data to the new block in response to the second command.

摘要： A recording medium stores contents and contents keys to be used for encrypting the contents, in a plurality of storage formats. The storage formats include a storage format (a first format) for delivered contents acquired through a network, and a storage format (a second format) for local contents acquired by a method other than the delivery. The intrinsic storage formats of the contents to be stored in the recording medium are determined according to the kinds of the contents. The recording medium stores not only the contents and the contents keys but also original storage format information (an import flag) (851) which is information indicating the intrinsic storage formats of the contents. With reference to the original storage format information, a reproduction device selects a reproduction method in accordance with the intrinsic storage formats of the contents.

摘要： Area management information is cached in a cache memory by controlling the access size when an information processor accesses the area management information in an information recording medium. When the processing content of the information processor is to retrieve a free area from the area management information, a physical management block size determined from the physical characteristics of the information recording medium is used. When the processing content is to acquire a link destination from the area management information, minimum access unit of the information recording medium is used. Consequently, overhead can be lessened when the area management information is accessed.
