摘要： A nonvolatile storage device is provided with a nonvolatile main storage memory (114) whose erase size is larger than a cluster size, and a buffer (106), i.e. a nonvolatile auxiliary storage memory. At the time of writing data in the memory, the data is temporarily stored in the buffer (106), then, a plurality of data in the buffer (106) are collectively taken out to be stored in the main storage memory (114). Data in an original block is saved in a write block in the main storage memory. Thus, the data can be written in the main storage memory (114) at a high speed.

摘要： In the present invention, a polarization having a lower polarization level than a saturation polarization is caused in a ferroelectric capacitor by applying a voltage that is lower than a saturation voltage to the ferroelectric capacitor. This allows a storage device to store many values by changing a length of a write-time during which the voltage is applied to the capacitor.

摘要： The power-supply unit, while directing externally supplied power to the control unit and the like, accumulates an amount of power that is required by the control unit to save data from the volatile memory to the non-volatile memory. When an external power supply has started, the control unit restores data of the non-volatile memory in the volatile memory; and when the external power supply has stopped, the control unit saves data from the volatile memory to the non-volatile memory.
