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.

1. How many chips are needed to construct the required memory?
2. How many address lines are needed for the required memory?
3. How many address lines in one chip?
4. What is the size of the decoder used? (number of inputs and outputs)
5. Draw the organization of the constructed memory, showing the external connections necessary to construct the required memory.
