3-D RAM is closer than ever

With the support of 100 technology companies, the three largest computer chip manufacturers in the world agree on Uniform standard The next generation of , Which will be three-dimensional and ultra-fast

The new memory, called HMC, or "Cube Hybrid "will introduce a number of features that are expected to bounce the industry into the next generation of speed and power in computing technology.

The subject was mentioned in the past in the articles they dealt with In cooperation with Intel With other companies (Micron in this case) as well as IBM's joining and 3M manufacturing A special glue that allows to glue layers of chips On each other to create powerful 3-D chips.

two years ago, Micron addressed a standards organization that deals with standards (JEDEC) and sought to create a new standard for chips Three-dimensional.

Now, the standard has arrived, and is particularly ambitious.

Cube Connected in multiple channels to multi-core processor. Is that how the screw started?

Together with Micron, Hynix and Samsung, about 100 companies and early adopters of the technology announced their support for the new standard in order to advance it and make it an industry standard.

Using new technology and advanced production techniques, Micron's team of engineers has managed to build a memory structure that uses multiple layers of chips loaded over the memory control circuit (in previous generations, such as And DDR4, control circuits, or memory logic are integrated with the memory cells themselves), allowing it to use 70 less power for each bit of memory, while accelerating its operation speed up to 160 GB per second in a two-channel connection , Compared to 11 GB per second at, Or 18-20 GB per second at.

A huge reduction in energy consumption, an increase of 14 according to data transfer speed compared to , What else can you ask for?

The first memory devices are expected to provide volumes of 2, 4 and 8 GB only, but it's not hard to guess that this is just the beginning.

Another responsible for this impressive leap is the use ofTSV - Which enables the creation of conductive transitions on the sides of the silicon itself (as opposed to regular circuits where the conductors are burned on the circuit) and vertically (from the bottom up). In the new generation of TSV technology, which uses these chips, the conductors are built into the chip (rather than on its sides), allowing small size to be maintained and the need for additional layers to be avoided.

In addition, the physical distance between the new memory sockets and the processor is significantly shortened, and this simple change will speed up the practical speed of the new memories.


A little long, but definitely interesting (Interview from 2011)

"This milestone marks the breaking of the memory barrier," claims Robert Feurle, vice president of marketing micron DRAM. "A device that has gained overwhelming support from the industry will help the fastest adoption of HMC technology, and we believe this will lead to radical improvements in computing systems and ultimately consumer products."

Since today there are significant needs in the area of ​​powerful computing, as well as communications products (such as high-speed optical routers and hubs) that are thirsty for memories and other components that can meet the increasing rates they offer, there seems to be no problem in terms of demand for components In the new standard.

Each component in computer systems whose speed increases is another bottleneck that opens and allows an additional increase in the power and speed of the processor and graphics card (for example) that may have been limited by them.

But do we, as consumers, need another jump in the speed of computers? Today companies are leading market like Concentrate on improving their existing product and polishing it more than adding cores or other drastic changes. There's a certain saturation feeling that might come from the consumer market that says "Enough. I really don't need another speed, Faster or any other major hardware enhancement. ”Maybe it's time to concentrate on the severely retarded software hardware that went through it more than ten years ago?

For regular operations, and even for heavy games and playing high definition content, it is now possible to purchase a relatively inexpensive computer (2500-4500 NIS) that will satisfy our needs for at least the next two or three years. There are also those who are satisfied with their computer for ten years or more!

  1. Excellent When does the PC market come?
    What is really interesting here is when the same product will reach the PC market, even though expensive SSDs were terribly expensive at the time.

  2. Oren Eyal
    Well done to the article.
    Just let me remark to you,
    I don't see a bottleneck in the way you explained your words - try to see how you interpret things.
    Another thing, today it is impossible to buy a computer at 4000 and say that it can be used for up to 3 years while we are constantly seeing the need for more powerful computers and especially better graphics cards.
    You could say that the last part of the article is a little unconnected with the existing reality.

    But big time, I wanted an article.

  3. True, there is saturation, but improvement is the picture
    Up to 160 Gb / sec transfer rate will revolutionize the industry and translate to major changes in operating system renovation This is the way to change the nature of future use of all computers.

  4. Thanks, but the last part was an opinion
    And not a translation. I definitely see a slowdown in demand for more powerful computers - if you look a few years back, you'll see that the race to a faster processor, or more powerful video card was much more intense and now Intel, AMD, and NVIDIA are relatively freezing in place. There is no increase in the number of cores - because there is really no demand for this with the demand for weight shifting towards tablets and mobile and lightweight devices. So I definitely think that the vast majority of users will have enough 4000 computer for a good few years.

  5. Tell Levy from Facebook:
    Thanks for the correction, I changed and clarified the point in the article.

  6. Definitely depends on needs
    It is very simple, the computer will hold according to the needs of the same user.
    Usually, people look for computers on the Internet and simple software that runs on any computer today at a very reasonable price.
    The Internet, like the other basic operations, no longer needs processing power (of any kind) over time, and certainly not exponential.
    Gamers, architectural designers, etc. are the ones who need the material changes.

  7. This will further reduce the most blessed motherboards and power consumption
    Power saving and huge performance improvement is most welcome..without looking forward to such a board.According to the chart, 2 Giga seems to function like 16 Giga memory due to proximity to the processor and 3D transfer to memory structure.Real Breakthrough..When Already in Ibori ..?

  8. What a beauty…. USELESS
    What helps me move TB in a second if it still takes a minute to get into the game because the hard disk is so much slower!
