You are asked to design a memory system using four memory chips. The chips used are four million (1 million = 2^20) address by four bit words. Consider an eight million address by eight bit word memory system. A) Answer the following questions. 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? to B) Now design the system below. Be sure you label the memory system inputs, Addr, R/W, and MemSel, and the system's outputs D0, D1, D2, etc. Also label containing and inputs and outputs of a required decoders. Put a star on the chips memory location 0
