    摘要: According to one embodiment, a free blocks included in a nonvolatile semiconductor memory are classified into a plurality of free block management lists. When a free block is acquired at normal priority, the free block is acquired from the free block management list in which a number of free blocks is larger than a first threshold. When a free block is acquired at high priority, the free block is acquired from the free block management list irrespective of the first threshold.

    摘要: According to one embodiment, a controller controls writing into and reading from a storage apparatus that includes a first data-storage unit and a second data-storage unit. The second data-storage unit stores user data and parity data of the user data. The first data-storage unit stores the parity data. The controller includes a parity updating unit and a parity writing unit. When parity data is updated, the parity updating unit writes the updated parity data into the first data-storage unit. When a certain requirement is satisfied, the parity writing unit reads the parity data written in the first data-storage unit, and writes the parity data thus read into the second data-storage unit.

    摘要: A scheme for image selection in an image transmission system for transmitting images from an image source to an image display device, capable of eliminating a need for the viewer to select the desired image by actually watching individual images and easily selecting the desired image in which a specific desired target of the viewer is shown. Feature information for identifying targets shown in each image is obtained, while a desired feature information for identifying a desired target specified by the viewer is entered. Then, the desired image which contains the desired target specified by the viewer is selected according to the obtained feature information and the entered desired feature information. The feature information may be obtained by recognizing targets shown in each image provided by the image source, or may be generated in advance in correspondence to images provided by the image source.

    摘要: According to one embodiment, a memory system includes a non-volatile semiconductor memory, a block management unit, and a transcription unit. The semiconductor memory includes a plurality of blocks to which data can be written in both the first mode and the second mode. The block management unit manages a block that stores therein no valid data as a free block. When the number of free blocks managed by the block management unit is smaller than or equal to a predetermined threshold value, the transcription unit selects one or more used blocks that stores therein valid data as transcription source blocks and transcribes valid data stored in the transcription source blocks to free blocks in the second mode.

    摘要: According to one embodiment, a memory system includes a nonvolatile memory, a managing unit, an order rule holding unit, a position information storing unit, a list selecting unit, a block selecting unit, a writing unit, and an updating unit. The managing unit holds for each of storage areas of the nonvolatile memory a free block list indicating free blocks. The order rule holding unit holds an order rule used to determine an order of the free block lists. The position information storing unit stores position information indicating the position of the free block list in the order rule. The list selecting unit selects the free block list corresponding to the position indicated by the position information and the block selecting unit selects the free block therefrom. The updating unit updates after the list selection the position information in the position information storing unit with position information indicating the position of the subsequently selected free block list.
