WebMemory mapped IO uses one address space for memory and input and output devices. In other words, some addresses are assigned to memory while others are assigned to store the addresses of IO devices. There is one set of read and write instruction lines. The same set of instructions work for both memory and IO operations. WebMemory-mapped input and output (MIOO) is the name given to this system. Generally, the assigned address is at the top of the address space.

Webmemory-mapped I/O. These I/O methods differ in how I/O ports are mapped into the 8086’s address spaces. Some microcomputer systems employ both kinds of I/O- that is, some peripheral ICs are treated as isolated I/O devices and others as memory- mapped I/O devices. Let us now look at each of these types of I/O. Isolated Input/ Output Method:
