Moving up to DDR2 at printed circuit board layout

Designing faster processors is the order of the day in the computing industry. However, processor speeds continue to exceed memory latency improvements. Although CPU speeds double every eighteen months, memory speed takes about ten years to double. This has given rise to the term “memory wall” to describe how overall system performance is bottlenecked by memory latency. Because of this, next-generation systems call for newer memory architectures able to withstand increasing demands of bandwidth and speed.
