Hello @qli.3 ,
Thank you for your question!
To ensure a timely response, I recommend posting questions in English which is the main working language across teams at ST.
To support you in your request, I translated your question via google translate. Please feel free to double check if it is correct and make necessary adjustments by commenting:
"In my use, some parameters are configured in the flash memory of the microcontroller (STM32F446ZET6), but the parameters are lost in unknown situations. There is a power off and power on operation before the power off. What is the cause of this, please? What is the solution?"

It's a process
It requires voltage and current to generate charge
If you try to erase or write flash into a collapsing supply you are prone to find the failure window.
>>What's the solution?
Use Journalled writing of data
Use Integrity checking
Use Redundancy, store data in more than one place
