DDR4 Memory to Feature Point-to-Point Topology

The next-generation DDR4 SDRAM memory will bring rather ultimate performance improvements to both desktops and laptops as well as servers and workstations. But the new performance heights will demand a rather radical change to topology of memory sub-system.

At a recent MemCon conference in Tokyo, Japan, Bill Gervasi, vice president of engineering at US Modular and a member of the JEDEC board of directors, revealed that the target effective clock-speeds for DDR4 memory would be 2133MHz - 4266MHz, an increase from previously discussed frequencies.  Apparently, JEDEC and memory manufacturers decided that the progress of DDR3 leaves no space for DDR4 data rates below 2133Mb/s.
