Hmmm. Perhaps this is a situation in which using something like a
DiskOnChip might be useful. The DiskOnChip ASIC isolates the flash bus
from the host and gives you a sensible pipeline for data transfer;
dual-host-cycle read/write accesses when appropriate.
Otherwise yes, you need to invent the same kind of thing to meet the
timing constraints of the NAND chip.
