In the nRF5 SDK there is a flash data storage module that can be used to store data:

This can be used to store away some state of the program, however you should be somewhat careful not to use it very frequently and not to store too much data, you can wear out the flash if you for instance write to the same memory address >10000 times.

Thank you for your comment. I wonder if you have any suggestions that I can use to achieve, for example, like Windows, when the power lost by accident, next time when I turn on the computer, the document opened in Word is still at the state before the power failure.

I am not aware of any such way, I think it would be extremely complicated (maybe impossible, considering that states of peripherals may not be the same).
