Disk How many address wires are there for an mxn memory? A. m B. n C. mxn D. 2m E. logz(m) 5. How many data wires are there foran mxn memory? A. m B. n C. mxn D. 2 E. log2(m) 7. Which sentence describes a memory write operation? A. Given an address, the memory outputs the data at that address B. Given an address and data, the memory saves the data at that address. C. Given some data, the memory outputs the corresponding address. D. Given some data, the memory saves the address of the data. E. Transfer data from disk to the CPU 6. Why is it important to use flip-flops instead of latches to construct a finite state machine? A. Flip-flops are the only way to provide the speed necessary for reliable finite state machine operation. B. The reduced speed of flip-flops is necessary to ensure reliable finite state machine operation. C. Flip-flops cost less than latches, so you have to use flip-flops to obtain the most economical implementation possible D. Flip-flops use less power than latches, so their use is important for optimizing battery life E. Flip-flops will never change state more than once per clock cycle, which is essential for designs like finite state machines where the outputs of the machine feed back into the inputs
