STM32F429I-Disco SDRAM disable question

I have the STM32F429I Disco board and would like to use more GPIOs than the 27 free ones available in the current board configuration.

I see that 38 pins are used by the SDRAM. I have not been able to find more specific information about how the SDRAM works or what it is used for.

Where can I find explanations of how the SDRAM pins are used and whether or not I can disable the SDRAM function and use the pins for GPIOs?

Thank you.
