High Performance Memory Systems

The State of Memory Technology Over the past decade there has been rapid growth in the speed of micropro­ cessors. CPU speeds are approximately doubling every eighteen months, while main memory speed doubles about every ten years. The International Tech­ nology Roadmap for Semiconductors (ITRS) study suggests that memory will remain on its current growth path. The ITRS short-and long-term targets indicate continued scaling improvements at about the current rate by 2016. This translates to bit de
