The maximum size of each DRAM block is 1GB.
Falcon Chipset
The Falcon chipset consists of two identical Falcon ASIC devices; The
upper Falcon and the lower Falcon. The upper Falcon connects to the
upper half of the system data bus, DH00 through DH31, while the lower
Falcon connects to lower half of the system data bus, DL00 through DL31.
