How can the Digital camera and Mp3, Smart phone or something else
save the data when they are turned off??

The reason why they have the NAND flash memory can save the data without the power.

The nand flash memory is non-volatile saving system with lower using power and no erasing data
Even though it is turned-off.
Its different with DRAM.
Conventionally, we use dram for memory cuz of faster speed.
Recently, the nand flash memory is used much more than dram.
The reason why the nand flash memory is non-volatile and has floating gate
can be used for many electronics.
Also, the capacitor has complicated circuit and large volume.
On the other hands, the floating gate has very simple circuit.

For these reasons, the nand flash memory can save lots of data with small space.
