You might take a look at drivers/mtd/nand/nandsim.c

It emulates NAND in RAM but I think it will be problematic to allocate
256 MiB of memory. But you may think of some trick... Nonetheless, I
used it to emulate 64MiB flashes and it works fine and even may emulate
some delays. I also may perform logging of NAND operations.

Cheers,
Artem.
