Korean microelectronics standardization body JEDEC Solid State Technology Association has ratified next-generation DDR4 SDRAM standard. The new development was announced through a press release on September 25. The JEDEC DDR4 (JESD79-4) standard has been defined to ensure higher performance with improved reliability and reduced power.
The per-pin data rate of DDR4 is set to be 1.6 giga transfers per second (GT/s) at the minimum and 3.2 GT/s at the maximum, initially. The standard encompasses DRAMs from 2 GB to 16 GB. Bus speed of DDR4 SDRAM will begin at 2,133 MHz.
Chairman of JEDEC’s JC-42.3 Subcommittee for DRAM Memories, Joe Macri said, “The publication of the JEDEC DDR4 standard represents the culmination of years of dedicated effort by memory device, system, component and module producers worldwide. The new standard will enable next generation systems to achieve greater performance, significantly increased packaging density and improved reliability – with lower power consumption.”
You can download the full DDR4 SDRAM (JESD79-4) standard from JEDEC website.
JEDEC has also arranged a two-day DDR4 Technical Workshop in Santa Clara, CA from October 30 to October 31. If you are interested to attend this workshop, you can register online.
