SRAM 0.5-5ns $4000-$10,000/GB in 2004 • DRAM 50-70ns $100-$200/GB in 2004 • The goal is to present the user with as much memory as is available with the cheapest technology, while providing access at the speed offered by the fastest memory. • Because all programs spend much of their time accessing memory, the memory system is necessarily a major factor in determining performance.
