Given a computer with 16-bit data bus and 20-bit address bus, what is the maximum memory capacity? Design the memory using the 128k × 8 memory chip shown below.
For 20-bit address, maximum memory capacity is 2^20 = 1 MB.
For a 128K x 8 memory chip, we will have 17 address lines. Please define more about the design procedure.
