JEDEC Announces Key Attributes of Upcoming DDR4 Memory 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.

"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. The per-pin data rates, over time, will be 1.6 giga transfers per second to an initial maximum objective of 3.2 giga transfers per second. With DDR3 exceeding its expected peak of 1.6 GT/s, it is likely that higher performance levels will be proposed for DDR4 in the future. Other performance features planned for inclusion in the standard are a pseudo open drain interface on the DQ bus, a geardown mode for 2667 Mhz data rates and beyond, bank group architecture, internally generated VrefDQ and improved training modes."

NOTE : JEDEC may not have released the final spec yet but Samsung made the first DDR4 memory chip announcement in January of this year—a 2133MHz device built with a 30nm process technology.MORE...

But according to Banglagamer DDR4 memory will not be coming out until 2014 though,so don't get too excited.
