摘要： To provide a nonvolatile storage device and control method thereof which improve convenience of portable devices by shortening initialization time. In generating a data validity table at initialization, a control part firstly reads out a validity flag and a second translation table. In the case where the validity flag is valid, logical blocks in the second translation table are valid. For that reason, the fourth table generation means can set all logical blocks in the second translation table as being valid, in the data validity table. In a single reading as mentioned above, the fourth table generation means can carry out setting with respect to a plurality of logical blocks. Further, with respect to a partial logical block which is set as being valid in the data validity table, it is possible to bypass reading out the data validity flag of the block and proceed to operation of next partial logical block.

摘要： A nonvolatile storage device includes a controller and a nonvolatile memory. The controller has: a logical-physical address conversion part for converting a logical address designated by a host device into a physical address; and a boot code address conversion part for converting boot code address information designated by the host device into a physical address. After the power-on and before the logical-physical address conversion part becomes usable, a boot code is read from a part of region which can be accessed by designating a logical address from the host device by designating the boot code address information from the outside. Thus, it is possible to rapidly start the nonvolatile memory system after the power-on. In the state where the logical-physical address conversion part can be used, data-reading and data-writing are carried out by designating a logical address from the host device.

摘要： 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.
