Correct. Provided the chip supports random reads (most do, I believe),
your in-tags ECC is sufficiently complex for the NAND part (multiple
plane chips could make life interesting - check the data sheet for
recommendations), and you take care to not send any hardware ECC unit
into conniptions, I think you're looking at a worthwhile speed-up,
especially on boards with a relatively slow clock speed. The downside,
of course, is that you lose however many bytes of every page to the tags
ECC as well as the tags themselves.
