I believe it was originally used to talk to NAND chips directly (which multiplex command/address/data on the bus, and use the "address" lines as chipselects), but is sufficiently configurable that it can be used as a generic address/data bus.mahjongg wrote: I'm very curious as to what the secondary memory interface is good for. I noticed it has a wide data bus, but only a few address lines, so it it for some kind of paged block mode flash device, like a K9K2G16Q0M, or for some kind of FIFO RAM?
Or something else altogether.
Is it possible to add a fast swap mechanism (virtual memory) using it?
Or, I'm speculating even more, for a SATA interface....
There's several peripherals on the general distribution market that could theoretically talk to this interface.
