Silego announces world’s lowest power GreenDDR3 register

SANTA CLARA, USA: Silego Technology, a leading fabless semiconductor company, has announced the industry’s first universal GreenDDR3 register. Silego’s SLGSSTE32882U covers all DDR3 speed grades from 800 to 1600 MHz and voltage rails from 1.25V to 1.5V with up to 40% less power consumption compared to competitive DDR3 registers.

Silego’s GreenDDR3 product line contains two types of registers. Version A is the world’s lowest power DDR3 register is fully JEDEC complaint and approved, and consumes up to 15% less power. Version B of the GreenDDR3 register is also compliant to JEDEC standards with the added feature of “Dynamic IBT,” a unique Silego technology that yields an additional power saving up to 40 percent.

DDR3 registers allow a greater number of DRAM modules to be placed on a server motherboard. However, these high performance memory modules consume vast amounts of power and require extensive cooling systems. Numerous industry initiatives exist to reduce memory module power while increasing memory density and performance.

Silego’s universal GreenDDR3 registers support all module power rail voltages, and meet the latest industry power-reducing initiatives by supporting 1.25V power rails. In fact, the energy saved by Silego’s GreenDDR3 register will more than pay for the cost of all registers over the server’s life time.

Silego, one of the world’s largest suppliers of timing products, leveraged its PLL design expertise to achieve lowest jitter, reduce system timing, and optimize voltage margins down to 1.2V. Silego’s universal GreenDDR3 registers removes speed screening and associated inventory costs, and has an advanced BIST “built in self-test” feature, which reduces test time and cost.

“Silego is pleased to be able to support industry initiatives that take advantage of the latest power-saving technologies,” said John McDonald, Vice President of Marketing and Sales. “The massive and continuous build out of fast communication services would increase global energy demand if not for aggressive efforts by server manufacturers to save every watt of energy possible.”
