Memory addressing in 8086
Web8086 Memory Addressing The 8086 memory address space can be viewed as a sequence of one million bytes in which. any byte may contain an 8-bit data element and any two consecutive bytes may contain a 16-bit data element. There is no constraint on byte or word address boundaries. The address space is physically connected to a 16-bit data … WebMost 8-bit CPUs could address at least 64k of memory with a 16-bit address bus. The 8086 was 16-bit but had a 20-bit address bus to allow more addressable RAM. The original AMD Opteron is 64-bit but the physical address bus is 40-bits (internally) to simplify the design of the memory subsystem, since the a full 64-bits is too large to be utilized.
