More like a PCie storage device with DMA no?

Sorry if that's pedantic lmao, but I feel like even the GBA ram blew nonvolatile storage out of the water

I'm not sure about GBA architecture specifically, but earlier systems just plugged those into the system bus directly.

According to here the ROM is directly on the bus, but since ROMs are slower than RAM, there is a cache-like buffer in between. But it's not a separate IO bus, it's still the memory-mapped system bus.

That's pretty cool, so like DMA but because the hardware couldn't (directly) tell the difference instead of an actual standard

Serves a similar purpose but closer to a cache memory than a DMA. It is not explicitly programmed for block access.
