Well, it only has 20 address bits. But it can address much more memory
because it has additional information on some status pins about what
segment register is used for adressing. So in theory, you could have one
separate 1Mb of memory for each possible segment register. Or at least you
could easily separate the stack from the other memory.
Anyone here know of a design that actually made use of this?
