Think of each bit doubling the address space available.
If a computer has a memory organization of 16-bit words and a total memory size of 2^30 bytes, how many total addresses are possible?
Use division to relate memory size to word size.
Design a modular memory system for a 1MB memory using 256KB chips. Explain how you would set up the address bus.
