    why don't just read the datasheet? A simple Google search shows that Z80 uses 16-bit address which means it can have at most 64KB of RAM – phuclv Aug 29 '18 at 09:40

The Z80 has a 16bit address bus, therefore it can only address at most 64KB of memory. It also has a separate I/O control line, which means that bank switching circuitry can be implemented so that the maximum usable memory is increased beyond this limit.
