Although we have seen many improvements in CPUs over the past few years, improving main memory to keep pace with the CPU is actually not as critical because of the use of cache memory. Cache memory is a small, high-speed (and thus high-cost) type of memory that serves as a buffer for frequently accessed data. The additional expense of using very fast technologies for memory cannot always be justified because slower memories ...
