WebJul 18, 2024 · If the address bus determined the "CPU size" then either these would have been called 16-bit systems or the systems would have been limited to 256 bytes of memory. Similarly, the 4-bit 4004 operated on 4-bit words but had a 12-bit address bus and could access 4k of memory - actually a little more - 4k ROM plus 640 bytes of RAM. Share WebSep 28, 2024 · Please clarify if you mean using a memory with 16-bit data or 16-bit address bus. Because both are possible as long as the memory is still byte-addressable. Or if you are willing to waste half of it. The memory size is not a problem, in theory you can connect as much memory as you want to a 8-bit processor, be it 1 megabyte or 4 gigabytes. – Justme

WebOct 5, 2014 · It is often the case that the address bus is the same size as the internal native architecture purely because that's convenient. However, it is not always the case. Take the Z80 CPU. It's an 8 bit CPU, yet it has a 16 bit address bus. One memory "cell" contains either a 1 or a 0. It is one bit.
