The development of DDR began in 1996, before its specification was finalized by JEDEC in June 2000 (JESD79). JEDEC has set standards for data rates of DDR SDRAM, divided into two parts. The first specification is for memory chips, and the second is for memory modules. The first retail PC motherboard using DDR SDRAM was released in August 2000. DDR4 Memory Supports 1866/ 2133/ 2400/ 2667Mhz (by JEDEC) Supports 2667/ 2800/ 2933/ 3000/ 3066/ 3200/ 3466 MHz (by A-XMP OC MODE) Jedec - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online.

Jedec said a DDR4 voltage roadmap has been proposed thatwill facilitate customer migration by holding VDDQ constant at 1.2V andallowing for a future reduction in the VDD supply voltage. DDR4 will helpprotect against technology obsolescence by keeping the I/O voltage stable,Jedec said. JEDEC’s DDR5 Announcement certainly came as no surprise to those of us working on the standard behind the scenes. The new 5th generation memory bus will have two, 32 bit channels complete with its own Address/Command and Control signals. to run at DDR4-3200 at a low latency timing of 16-18-18 at 1.35V. The SPDs are programmed to JEDEC standard latency DDR4-2400 timing of 17-17-17 at 1.2V. Each 288-pin DIMM uses gold contact fingers.
