Using external sram?
You can use one of the many SPI/QSPI PSRAM chips that are available. If you don't need to have it have it mapped as actual memory that you can malloc, using it should be pretty straightforward. I've written a library to help interface with SPI PSRAM over PIO & DMA, and I've tested it at up to 140MHz (with the RP2040 running at 280MHz): https://github.com/polpo/rp2040-psram
