Abstract: In a transponder serving as a functional device having plural units, I/O RAM for holding functions settings contents is prepared for two sides, i.e. an ACT side and a STBY side in each unit. When functions settings contents are to be modified, the unit CPU in each unit switches the I/O RAM from the ACT side to the STBY side. The units continue to operate by using the settings contents of I/O RAM on the ACT sides, but set new settings contents for the STBY sides. The CPUs instruct that new settings contents be set simultaneously, thereby each unit reads the settings contents of I/O RAM on the STBY sides, and sets functions in the LSI.

Abstract: An image pickup apparatus includes a solid-state image pickup device chip, an FPC whose terminals are connected to the solid-state image pickup device chip, and a plurality of electronic components mounted on a front surface of the FPC, wherein behind a back face of the solid-state image pickup chip, the FPC is disposed by being folded in such a way that the FPC will provide mounting surfaces for the plurality of electronic components in a plurality of layers and that the plurality of electronic components will be superimposed via the FPC.
