Maximum RAM supported by each bits:
Consider the memory limits of architectures:
- 8-bit: 64kb (if using 16 bit bus much less on 8 bit bus)
- 16-bit: 16mb (if using 24bit bus, much less on 16bit bus)
- 32-bit: 4gb (can be more on x86 systems if using PAE extension)
- 64-bit: 16 Exabytes | 16.8 Million Terabytes
