Design a block of the memory which is 512K x 8 bits using memory chips which are 128K x 8 bits. Assume that the chips are ROM with Chip Enable (CE) inputs and Output Enable (OE) inputs. How many address inputs do the individual chips have? How many total address lines are needed to decode the entire 512K? Show the decoder and indicate which address lines are used as its inputs and show how its outputs are to be used.
