Next-Generation DDR4 Memory to Reach 4.266GHz

DDR4 Memory to Feature Point-to-Point Topology

The next-generation DDR4 SDRAM memory will bring rather ultimate performance improvements to both desktops and laptops as well as servers and workstations. But the new performance heights will demand a rather radical change to topology of memory sub-system.

At a recent MemCon conference in Tokyo, Japan, Bill Gervasi, vice president of engineering at US Modular and a member of the JEDEC board of directors, revealed that the target effective clock-speeds for DDR4 memory would be 2133MHz - 4266MHz, an increase from previously discussed frequencies. Apparently, JEDEC and memory manufacturers decided that the progress of DDR3 leaves no space for DDR4 data rates below 2133Mb/s.

The designers of DDR4 memory are looking forward 1.2V and 1.1V voltage settings for the new memory type and are even considering 1.05V option to greatly reduce power consumption of the forthcoming systems. It is expected that manufacturers of dynamic random access memory (DRAM) will have to use advanced fabrication technology to make the DDR4 chips. The first chips are likely to be made using 32nm or 36nm process technologies.

At present JEDEC expects to finalize the DDR4 specification in 2011 and start commercial production in 2012. Actual mass transition to the next-generation memory is projected to occur towards 2015.

How fast do we really need? Does it matter if it takes 1 nanosecond or .5 nanosecond to access memory, for example. Everyone is obcessed with speed but at the Gigabit speeds does it really matter if it runs at 3.2 or 3.4GB?

Because they can:devil:

There is no way to stop human innovation - and that is good. There will be always applications for faster and better. But that does not mean that everybody will have to jump on the bandwagon immediately. Initial pricing usually prohibits that anyhow (example: SSDs).

Someone will find a way to utilize it, we're still not at instantaneous load times

Remember what they said about processor speed and storage size just 10 years ago.

Something to the effect - We don't need anything faster or bigger.

We'll reach that point some day, but then there's actual component size to work on.

what happens when we reach the physical limit of speed possible though?

Then the physical limit will be pushed

Hopefully by then carbon nanotubes or something will be used.

In an increasingly transactional world, every slice of time counts. Think of how many people visit Ebay or Amazon.

While this may be slightly off topic, I watched an interested show the other day about the advancement of computer technology.

Apparently, according to the documentary, they are advancing so fast they must start looking for alternative means of creating CPUs.

Such as CPUs being based on organic technology, rather than silicon.
According to the show, silcon is getting to the point there simply isnt much more room for advancement.

The physical limitations (in this case, simply space on the chips) to put millions and millions of transistors is running out. They are looking at alternatives, but those are somewhat far off. They already know that the silicon melts when it is spread too thin and a current is run through.

In fact, they discuss it in a show about Jan Hendrik Schon that I watched.
