Can you think of a reason why ROMs tend to be nonvolatile and RAMs volatile?

Consider the Pentium processor with an 800-MHz front-side bus. What is the bandwidth of this bus?

 We stated that DDR SDRAMs and RDRAMs compete for the high-end systems that

require higher bandwidth to support 533-MHz FSB. Suppose we use a four-channel

RDRAM memory subsystem. What is the clock frequency that this subsystem should

operate in order to meet the bandwidth requirement of the last question?
