How to store temporary more data?

Hello,

I'm using the STM32F405 microcontroller.

For my application/calculation I need to store temporary a lot of data, which exceed my SRAM.

To expand it, without using an external SRAM, I had following ideas:

- Use the Backup-SRAM as common SRAM (only 4kB).
     Question: Is there a write limitation e.g. 100.000 write cycles?

- Store some data in the flash memory.
     Question: How can I configurate the linker to keep e.g. the last 100kByte free?
     Do I just need to reduce the parameter “__Main_Stack_Size”  from 1024 to 924


Thank you
