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 a) [I mark] How many chips are needed to construct the required memory? b) [I mark] How many address lines are needed for the required memory? construct the memory with the given chips and a decoder. c) [I mark] How many address lines in one chip? d) [I mark] What is the size of the decoder used? (number of inputs and outputs) e) [2 marks] Draw the organization of the constructed memory, showing the external connections necessary to construct the required memory
