Routing external memory to a nucleo board using FMC memory controller

Afternoon everyone,

I'm not sure of how to do this, but I need to store a large amount of data on my mcu(around 4 times larger than the SRAM the mcu has), for a brief period of time. I'll be using the nucleo-F722ZE (

STM32F722ZE

 )

.

It has a flexible memory controller, so in theory I think I can map SRAM to the board through the FMC and use the DMA to quickly store the data as it comes in. I just want to double check if this is possible and how much slower would it be than accessing internal SRAM.

I'm thinking of using the following SRAM:

Any help would really be appreciated as this is not something I'm at all familiar with.

Thanks in advance.
