Haven't actually timed it (yet) but I think it'll all work out just fine.

If there's any interest I'll post the code in the Code Examples section.

Thanks again, everyone, for all the suggestions.

Actually I could use SHIFTIN and SHIFTOUT for accessing the F-RAM memory, as you told, it is a "comedy" wiring error, it seems like totally reversed. But for hardware SPI, I think the MISO,MOSI connection should be followed, right? In your code, it is connected like this.
