Retrieved 12 October CL — CAS Latency clock cyclesbetween sending a rdr3l address to the memory and the beginning of the data in response.

This significant reduction in power consumption, especially in memory-intensive systems, will have dramatic benefits in areas such as power supply demand, system cooling requirements and potential packaging density. DDRDand capacity variants, modules can be one of the following:.

Of these non-standard specifications, the highest reported speed reached was equivalent to DDR, as vdr3l May In other projects Wikimedia Commons.

JEDEC Publishes Widely Anticipated DDR3L Low Voltage Memory Standard | JEDEC

Bandwidth is calculated by taking transfers per second and multiplying by eight. From Wikipedia, the free encyclopedia.


The CPU’s integrated memory controller can then work with either. Because the hertz is a measure of cycles per second, and no signal cycles more often than every other transfer, describing the transfer rate in units of MHz is technically incorrect, although very common.

The actual DRAM arrays that store the data are similar to earlier types, with similar performance. Archived from the original ddrr3l It is typically used during the power-on self-test for jedwc configuration of memory modules.

Retrieved 19 March For the graphics memory, see GDDR3. All articles with unsourced statements Articles with unsourced statements from March There is some improvement because DDR3 generally uses more recent manufacturing processes, but this is not vdr3l caused by the change to DDR3.

This advantage is an enabling technology in DDR3’s transfer speed.

High-performance graphics was an initial driver of such bandwidth requirements, where high bandwidth data transfer between framebuffers is required.

Retrieved 12 December Retrieved from ” https: The DDR3L standard is 1. Over 3, participants, appointed by nearly companies, work together in 50 JEDEC committees to meet the needs of every segment of the industry, manufacturers and consumers alike.

Another benefit is its prefetch bufferwhich is 8-burst-deep. 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.

The Core i7 supports only DDR3. Archived from the original on December 19, Continuing the evolution of DDR3 as the dominant DRAM standard today, DDR3L will enable a significant reduction in power consumption for a broad range of products that utilize memory; including laptops, desktops, servers, networking systems and a wide array of consumer electronics products. Archived from the original on April 13, Devices that require DDR3L, which operate at 1.


Some manufacturers also round to a certain precision or round up instead.

This article is about the computer main memory. Media Inquiries Please direct all media inquiries to: DDR3 memory utilises serial presence detect. DDR3 modules are often incorrectly labeled with the prefix PC instead of PC3for marketing reasons, followed by the data-rate.

This is because DDR3 memory modules transfer data on a bus that is 64 data bits wide, and since a byte comprises 8 bits, this equates to 8 bytes of data per transfer.

Archived from the original PDF on This page was last edited on 17 Novemberat DDR3 prototypes were announced in early Solid State Memories JC This reduction comes from the difference in supply voltages: Rapid introduction will be facilitated by the fact that the fundamental specifications have not changed, and many systems ejdec require only minor modifications ddrr3l order to adhere to the jeeec standard.

Multiple Chip Packages JC Already available in limited supply with some manufacturers, 1. Memory standards on the way”. The publications and standards that they generate are accepted throughout the world.
