How do develop a high speed memory device?

One of the major problems faced by system designers is to reliably interface with their next generation high-speed memory devices. As system bandwidths continue to increase, memory technologies have been optimized for higher speeds and performance. As a result, these next generation memory interfaces are also increasingly challenging to design too.
