Abstract
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.
