Best answer 2 votes 2 votes Addition of two 8 bit numbers atmax can be a 9-bit number. and There are total $2^8*2^8$ combination of additions possible. So, Memory needed $= 2^8*2^8*9bit = 2^{16}*9bit$ (option A) thor answered Jan 10, 2017 • selected Jan 10, 2017 by Sushant Gokhale thor comment Share Follow See all 0 reply Please log in or register to add a comment.
