You forgot the "certain stack" 😉 compare it to the "standard" edition of fatFS and you´ll see, it IS small ...

If you don't know what a stack memory is, then start with learning that!

Thanks for reply but my question is still same, how much stack memory it will take and i think its not small memory, it takes over 300 bytes.

because value of data in keil shows 300 after compiling with memory error.

Observe in mapfile how exacrltly the data are allocated. There may be RAM area lost because of padding/alignment, or inappropriate choice of data width.
Optimization of any kind - here for minimal memory space - requires effort and understanding of the used tools (compiler, linker etc.).
