Using multiple 4M × 8 RAM chips (see below) plus a decoder, construct the block diagram of a 16M × 16 RAM system. Hint: 1 million = 2^20. 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? Now design the system below. Be sure you label the memory system inputs, Addr, R/W, and MemSel, and the system’s outputs D0~D15. Also label bus widths, and inputs and outputs of any required decoders. Put a star on the chips containing memory location 0.
