Note that PSRAM is just a DRAM with an easier interface. It's not at all comparable to true SRAM.

I don't think that's entirely true, but the 'p' is pSRAM does stand for 'pseudo' and does have refresh circuitry and is slower than true SRAM. By how much, I have no idea.

I mean having refresh circuitry basically means it's DRAM. that's one of the unique points of DRAM, it has to periodically refreshed.
