Question #7 (5 marks):

Construct a ROM memory with the size 128 x 8 ROM, knowing that in the lab, you only have ROM chips with the size of 32 x 8 chips with an enable input. You can construct the memory with the given chips and a decoder. [Hint: you can do this by dividing the address lines into two section; one section to address the chip (using chip Enable) and the other to address words within the enabled chip)
