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 densities increasing
at two times every two years until the introduction of 8 gigabit
dynamic random access memory (DRAM) chips, after which densities
will increase four times every five years. A similar growth pattern
is forecast for other high-density chip areas and high-performance
logic (e.g., microprocessors and application specific inte grated
circuits (ASICs)). In the future, molecular devices, 64 gigabit
DRAMs and 28 GHz clock signals are targeted. Although densities
continue to grow, we still do not see significant advances that
will improve memory speed. These trends have created a problem that
has been labeled the Memory Wall or Memory Gap."
