Two types of memory organization are used:
Linear addressing where the entire memory is available to the processor at all the times ( Motorola 68000 family).
Segmented addressing where the memory space is divided into several segments and the processor is limited to access program instructions and data in specific segments.

instruction register, which is actually a 6-byte queue, the control unit
and working registers are divided into three groups according to their
functions. There is a data group, which is essentially the set of
arithmetic registers; the pointer group, which includes base and index
registers, but also contains the program counter and stack pointer; and
the segment group, which is a set of special purpose base registers. All
of the registers are 16 bits wide.
The data group consists of the AX, BX, CX and DX registers. These
registers can be used to store both operands and results and each of
them can be accessed as a whole, or the upper and lower bytes can be
accessed separately. For example, either the 2 bytes in BX can be used
together, or the upper byte BH or the lower byte BL can be used by
itself by specifying BH or BL, respectively.

Why memory to memory acess is not possible in 8086 micro processor?
Memory to memory access is certainly possible in the 8086/8088 microprocessor. Look at the repeated string copy instructions.
What is the highest memory address?
The highest memory address in the 8086/8088 is FFFFFH.
What is memory interfacing in 8086 microprocessor?
The 8086/8088 is a 16 bit computer running on a 20 bit address bus. Processes use a segmented memory architecture to access one of four 64kb memory segments from a physical space of 1mb.
What is MR-DC in 8086?
Its MRDC (memory read control) it is a maximum mode pin in 8086 microprocessor
Why is the 8086 memory set up as 2 byte wide banks?
Because the 8086 is a 16 bit processor. Memory is organized as 512 MW of memory, or 1024 MB of memory.
Does 8086 has memory?
8086 does not have RAM or ROM inside it. However, it has internal registers for storing intermediate and final results.
How many memory address does this number of address lines allow the 8086 to access directly?
The 8086/8088 has 20 address lines. It can access 220, or 1MB, or 1,048,576 bytes of memory.
How many memory addresses does this number of address lines allow the 8086 to access directly?
The 8086/8088 has 20 address lines. It can access 220, or 1MB, or 1,048,576 bytes of memory.
What is the size of each memory segment of 8086 is?
The 8086 was only capable of addressing 1Mbyte of memory. It was divided into segments of 65536 bytes (64 KB) each meaning about 16 segments.
Can both operand 1 and operand 2 be memory in 8086?
Yes, both operand 1 and operand 2 can be in memory in the 8086. An example is the string copy primative, which takes source and destination operands to be memory pointed to by DS and ES.
8086 micro processor memory segmentation and advantage and rules?

What is memory organisation?
Memory can be organized into a one-word-wide organization, wide memory organization, interleaved organization and independent memory organization. The types of memory include HDD, RAM, ROM, and GPU.
