    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 control method of a non-volatile memory apparatus, which can execute data writing normally after the next startup even when a process is interrupted because of the occurrences of abnormal conditions such as power shut down during data writing or data erasing is provided. The control method of a non-volatile memory apparatus of the present invention comprises: a first flag writing step of writing a fixed value, which indicates that data is written, on a first flag existing in a redundancy area on a first page of a physical block and indicating whether or not data is written on the first page; and a data writing step of writing data on the physical block, when the data is written on the non-volatile memory consisting of a plurality of physical blocks.

    摘要： A communication system in which an operating voltage can be selected from a plurality of interface voltages enables an interface voltage to be switched in a stable manner during operation of the system. When the interface voltage is to be switched, a host device (1) and a slave device (2) perform the switching while maintaining the signal level of buses in a stable manner. This structure enables the communication system to switch an interface voltage using a small number of signal lines.
