Memory Addressing Modes

Memory (RAM) is the main component of a computer to store temporary data and machine instructions. In a program, programmers many times need to read from and write into memory locations.

There are different forms of memory addressing modes

1. Direct Addressing
2. Register indirect addressing
3. Based addressing
4. Indexed addressing
5. Based indexed addressing
6. Based indexed with displacement
