3. [20 pts] Using multiple 4M * 8 RAM chips (see below) plus a decoder, construct the block diagram of a 16M ~ 16 RAM system. Hint: 1 million = 220. A) [8 pts] Please answer the following questions. How many 4M ~ 8 RAM chips are needed? How many address lines does the memory system require? How many data lines does the memory system require? What kind of address decoder is required? B) [12 pts] Now design the system below. Be sure you label the memory system inputs, Addr, R/W, and MemSel, and the system's outputs Do-D15. Also label bus widths, and inputs and outputs of any required decoders. Put a star on the chips containing memory location 0. You can draw the circuit on a white paper using a ruler, and then, take a photo of it. Next, you can insert the photo here. Ao - A21 4 MX8 CS R/W Do-D7
