(PR) JEDEC Announces Key Attributes of Upcoming DDR4 Standard

JEDEC Solid State Technology Association, the global leader in the development of standards for the microelectronics industry, today announced selected key attributes of its widely-anticipated DDR4 (Double Data Rate 4) standard. With publication forecasted for mid-2012, JEDEC DDR4 will represent a significant advancement in performance with reduced power usage as compared to previous generation technologies. When published, the new standard will be available for free download at www.jedec.org.

DDR4 is being developed with a range of innovative features designed to enable high speed operation and broad applicability in a variety of applications including servers, laptops, desktop PCs and consumer products. Its speed, voltage and architecture are all being defined with the goal of simplifying migration and facilitating adoption of the standard.
A DDR4 voltage roadmap has been proposed that will facilitate customer migration by holding VDDQ constant at 1.2V and allowing for a future reduction in the VDD supply voltage. Understanding that enhancements in technology will occur over time, DDR4 will help protect against technology obsolescence by keeping the I/O voltage stable.
