Samsung now mass producing 128GB DDR4 modules using TSV interconnect technology

  1. Samsung on Thursday revealed it is now mass producing memory modules boasting the largest capacity and the highest energy efficiency of any DRAM module. The 128GB DDR4 sticks in question were made possible by utilizing the through silicon via (TSV) interconnect technique.

    Foregoing traditional wire bonding, the TSV technique involves grinding chips down to a few dozen micrometers, piercing them with hundreds of tiny holes and vertically connecting them with electrodes passing through the holes. Although not new, the advanced circuitry does allow for a significant boost in signal transmission.

    The 128GB modules are comprised of 144 DDR4 chips arranged into 4GB DRAM packages (18 per side for a total of 36), each containing four 20nm 8Gb chips. Samsung says the modules have a special design in which the master chip of each 4GB package embeds the data buffer function, further optimizing performance and power consumption.

    The end result is a module that offers speeds of up to 2,400Mbps which is nearly twice the performance and half the power usage as the previous highest capacity DRAM modules, 64GB LRDIMMs. Samsung said the previous capacity king was hampered by power and speed limitations due to its use of conventional wire bonding.

    As you’ve likely surmised by now, these modules are designed for enterprise server and data center applications.

    Samsung said it plans to roll out a complete lineup of TSV DRAM modules over the next several weeks in addition to boosting data transfer speeds up to 3,200Mbps.

    How I wish I could somehow obtain 4 or 5 of those... Even one would do! But we'll probably be fed 4GB and 8GB sticks for years instead, with such treats being reserved to the magical "enterprise" solutions...

    Why would you want so much RAM?

  7. How about an operating system that loads completely into DRAM when powered on? Think you would want a UPS to go with that though

    One such memory plank will cost as much as 10 times a quality hooker, therefore I'm not sure it's a good investment...

    I dunno. If they want it for everyday computing and gaming it's nothing more than a waste of money and RAM.

    The 1st two are a complete waste of time, money and effort but the last one is a solid investment. ;)

    I am a computer science professional. I would like a home processing "server" (or for a university). I do not want to have to send my simulations and data to remote servers.

    There is no meaning to "what would you use so much memory for?". It is not of anybody's business what I want to consume (unless it damages the environment).

    This is, possibly, a choice made for a reason. If it was a system vendor's choice, I would maybe understand that there is not enough of a customer base for such a product. But making servers out of more memory, when memory technology is a major economy of scale, is meaningless.

    I feel like I gained a couple of IQ point just reading your comment.

    Finally I can have 100 GB of RAM just like Weird Al.
