  • Patent number: 9124099
    Abstract: A storage battery is charged with power supplied from at least one of a commercial power system and an independent power source, and supplies the charged power to a plurality of electric devices or the commercial power system. A control unit switches the operation state of the storage battery to either charging or discharging, and switches connection destinations of the storage battery. When the commercial power system is not in a power outage state, the control unit supplies power from the storage battery to the electric devices or the commercial power system only if the remaining level of the storage battery exceeds a reference value.

  • Patent number: 9111649
    Abstract: There is provided a semiconductor device which is simple in configuration and resistant to tampering. A user input unit receives an authentication code input by a user. A CPU determines whether a user's access is legal based on the input authentication code and activates an enable signal if the user's access is legal. A normal row decoder decodes the row address specified by the CPU and selects a normal memory cell of any row based on the result of decode. A redundancy row decoder prohibits the selection by the normal row decoder when the specified row address agrees with the row address of a predetermined normal memory cell only if the enable signal is activated and selects a redundant memory cell of any row.

  • Patent number: 9111636
    Abstract: The gate tunnel leakage current is increased in the up-to-date process, so that it is necessary to reduce the gate tunnel leakage current in the LSI which is driven by a battery for use in a cellular phone and which needs to be in a standby mode at a low leakage current. In a semiconductor integrated circuit device, the ground source electrode lines of logic and memory circuits are kept at a ground potential in an active mode, and are kept at a voltage higher than the ground potential in an unselected standby mode.
