differenc between Memory mapped IO and Address mapped IO.

Memory mapped IO uses the same address space for Memory and IO devices addressing. What I would like to ask is memory space inside the processor is dedicated for both Memory and IO access, Is my understaing correct? its not the external flash memory right?

for IO mapped IO type separate memory will be allocated inside the processor for IO devices right?
