Suppose that an 16M x 16 main memory is built using 256K ~ 8 RAM chips and memory is word-addressable. 1. How many RAM chips are necessary? 2. To access one word, how many chips would be involved? 3. How many address bits are needed for each RAM chip? 4. How many banks will this memory have? 5. How many address bits are needed for all of memory? 6. If high-order interleaving is used, which bank would address Ox7C25D1 be located? (Using binary format to represent bank ID) 7. If low-order interleaving is used, which bank would address Ox7C25D1 be located? (Using binary format to represent bank ID)
