Checked and confirmed, it's 8K.
The docg3 has a mapped IO space, where :
 - 0x0 - 0x7ff     : boot memory (NOR like)
 - 0x800 - 0xfff   : data area
 - 0x1000 - 0x17ff : registers area
 - 0x1800 - 0x1fff : boot memory (the same one as before)

And the previous "64MB" was because I didn't know which kind of memory was
there, and a static bank can be as big as 64MB.

Cheers.
