    • When multiple pieces of content data are being recorded continuously to a nonvolatile storage device having page cache function, a preparation time before starting next content data recording is reduced. When a cache releasing section of a nonvolatile storage device (1) receives cache releasing from an access device (2), it releases addresses included in one logical block among multiple addresses which are cache objects at the same time. Further, the nonvolatile storage device (1) includes a cache information outputting section which outputs information regarding a time period required for releasing addresses which are cache objects outside, and the access device (2) refers to the information to select the address to be an object of releasing.
    • 当多条内容数据被连续地记录到具有页面缓存功能的非易失性存储装置时,减少开始下一内容数据记录之前的准备时间。 当非易失性存储设备(1)的缓存释放部分从接入设备(2)接收缓存释放时,它同时释放多个地址之中包含在一个逻辑块中的地址。 此外,非易失性存储装置(1)具有高速缓存信息输出部,其输出关于释放作为外部的高速缓存对象的地址所需的时间的信息,并且,访问装置(2)参照将该地址选择为 释放对象

    • 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.
    • 非易失性存储器件在访问设备以块大小的单位写入块中的所有数据时,防止数据写入中间向数据块写入数据时暂时减慢。 所述非易失性存储器件包括存储器控制器,所述存储器控制器包括被配置为接收标识用于写入数据的第一写入范围的第一命令的接口单元和识别作为所述第一写入范围的一部分的第二写入范围的第二命令, 将数据写入第二写入范围,地址管理单元,被配置为基于第一命令在数据被写入非易失性存储器之前确定用于将数据写入到第一写入范围的新块,并且配置为读/写控制单元 以响应于第二个命令将数据写入新块。

    • A method for increasing the speed of processing when writing multiple files in parallel and writing file data in a stable manner in the case where the regions of a non-volatile memory in an information recording module are managed according to a filesystem is provided. An access module (1) includes a unit (104) that communicates, to an information recording module (2), information regarding the storage location of a directory entry, and also includes a unit (105) that pads file data when writing fractional data such as the end of a file and writes that data into the information recording module (2). Upon determining that the directory entry is to be written based on the communicated information, the information recording module (2) stores the directory entry in a dedicated physical block. Furthermore, the access module (1) pads the data of multiple files as necessary and records those files in continuous addresses in units that are a multiple of a predetermined size of a unit of recording processing.
    • 提供了在根据文件系统管理信息记录模块中的非易失性存储器的区域的情况下,并行地写入多个文件并且以稳定的方式写入文件数据时提高处理速度的方法。 访问模块(1)包括向信息记录模块(2)传送关于目录条目的存储位置的信息的单元(104),并且还包括在写入小数据数据时衬垫文件数据的单元(105) 例如文件的结尾并将该数据写入信息记录模块(2)。 在基于所传送的信息确定要写入目录条目时,信息记录模块(2)将目录条目存储在专用物理块中。 此外,访问模块(1)根据需要填充多个文件的数据,并以这些记录处理单位的预定大小的倍数的单位将这些文件记录在连续地址中。
