摘要： A card information-storing portion is provided in a semiconductor memory card, and information relating to access performance such as access condition and access rate is held in the storing portion. Further, an access device acquires the held information from the semiconductor memory card to make it possible that the information can be used for control of a file system. This optimizes processing of the access device and the semiconductor memory card independent of differences in characteristics of semiconductor memory cards and management methods used, realizing high-rate access from the access device to a semiconductor memory card.

摘要： A host information memory is provided in a semiconductor memory card and a data write start address and a data size supplied by an access unit are stored. A free physical area generation section determines whether or not to perform erasing of an invalid block of a nonvolatile memory when writing of data based on the data write start address and data size, and determines the number of blocks to be erased. When erasing, writing of data and erasing of invalid blocks are simultaneously performed with respect to different memory chips. Erase process of data, herewith, can be optimized and high speed access from the access unit to a semiconductor memory card can be realized.

摘要： When a file system control part 155A writes file data into a main memory 142, a file can be easily written continuously and the number of file copy can be decreased at updating a directory entry by writing the file data and a directory entry into different allocation units. In this manner, when using a nonvolatile memory in which physical block size as an erase unit is larger than cluster size, the write performance can be enhanced.
摘要翻译： 当文件系统控制部分155A将文件数据写入主存储器142时，可以容易地连续地写入文件，并且可以通过将文件数据和目录条目写入不同的分配来更新目录条目来减少文件拷贝的数量 单位。 以这种方式，当使用物理块大小作为擦除单位的非易失性存储器大于簇大小时，可以提高写入性能。

摘要： A host device transmits a command from a command transmission unit (101a) along a predetermined command sequence. A storage device (2) receives the command in a command reception unit (202a). An access determination unit (202c) determines the sequence of the command transmitted from the host device (1) and determines that reception of the access to the host device (1) is enabled only when the sequence is identical with a predetermined sequence. Thus, with simple control, it is possible to prevent data destruction by a host device of an old version.
摘要翻译： 主机设备沿着预定的命令序列从命令发送单元（101a）发送命令。 存储装置（2）在命令接收部（202a）中接收命令。 访问确定单元（202c）确定从主机设备（1）发送的命令的顺序，并且确定只有当序列与预定序列相同时，对主机设备（1）的访问的接收才被使能。 因此，通过简单的控制，可以防止主机装置破坏老版本的数据。
