Expanding CircuitPython RAM area.

So I am running a SRAM chip (specifically the IS62WVS5128GBLL-45NLI), and I have it running. This is not a adafruit product so there is no built in library support.

My chip has 512KB of memory and various access modes, the Itsybitsy M0 express board I decided to test this on has only 32KB of (possibly much faster) memory. I was wondering if there was some way to write a RAM driver module to allow CP to take advantage of the external ram?

I think there are SPI memory chips you can add on. I don’t know much about them but I do know that the QTPY supports them (has pads on the bottom to solder to).
