Called DDR3L for DDR3 Low Voltage, devices adhering to the new standard will operate from a single 1.35V power supply voltage compared to 1.5V in existing devices. Under the new standard, DDR3L memory devices will be functionally compatible to DDR3 memory devices, but not all devices will be interoperable at both voltage ranges, JEDEC said.
The DDR3L standard defines the operating characteristics for DDR3L memory devices, with the devices offering a reduction in power consumption of 15% or more as compared to DDR3 (and 40% as compared to DDR2), when operating at the same performance and load capacity. This significant reduction in power consumption, especially in memory-intensive systems, will have benefits in areas such as power supply demand, system cooling requirements and potential packaging density.
Already available in limited supply with some manufacturers, 1.35V devices are forecasted to be widely available from suppliers, who have been working within JEDEC to ensure DDR3L compatible devices may be procured from multiple sources. Rapid introduction will be facilitated by the fact that the fundamental specifications have not changed, and many systems will require only minor modifications in order to adhere to the new standard.
John Kelly, JEDEC President, added, "The publication of DDR3L is an integral part of the ongoing effort within JEDEC to extend memory device technologies to meet the industry?s need for environmentally-friendly, high performance products."
