Master the secrets of system design using DDR4 SDRAM
It is rare that you get to sit at the feet of a certified master and learn. If you’re interested in designing with DDR4 SDRAM, then this is your chance. On Tuesday, October 25, at ARM TechCon, Marc Greenberg will … Continue reading
What’s it take to design DDR4 into your next SoC? Newly released DFI 3.0 Spec opens the flood gates for DDR4 design
DDR4 SDRAM probably won’t be appearing until 2013 and probably won’t become the mainstream SDRAM technology until 2015 (updated estimates from “Memory to processors: “Without me, you’re nothing.” DDR4 is on the way.”) but the new DFI 3.0 preliminary specification … Continue reading

JEDEC releases more details about DDR4 SDRAM spec. Want to know what they are?
Although DDR3 memory is just ramping up in sales, JEDEC has been working on the next-generation DDR4 specification for faster SDRAM that consumes even less power. To achieve these goals, JEDEC announced yesterday that has specified the following key features … Continue reading
The DDR4 SDRAM spec and SoC design. What do we know now?
DDR4 SDRAM is coming. 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—and Hynix followed suit in April … Continue reading
