Samsung V-NAND

New 3D chips offer at least twice the reliability and speed over 10nm chips.

Following the logical progression along flash storage development, Samsung has just announced that it will begin mass producing 3D "vertical NAND" (V-NAND) flash chips. Although we know Samsung as a massive consumer electronics company, the Korean manufacturer also has a lucrative business making the internal components — such as processors, flash storage and displays — for many different device manufacturers.

We've talked before about the move by Samsung (and other manufacturers) to smaller technology for fitting a denser amount of storage on the same physical area with the move to a 10nm-class manufacturing process, but as the name would lead you to expect this new 3D NAND system goes a step further. Rather than sticking to a traditional "planar" (flat) structure, Samsung is now building chips that stack components vertically — up to 24 cell layers high.

Just like moving to a smaller architecture, moving to V-NAND has inherent advantages in both reliability and speeds for the resulting chips. Samsung says that these first V-NAND chips are 2 to 10 times more reliable and have 2 times the write performance when compared to existing 10nm-class flash memory.

With mass production starting now, Samsung expects the new chips to be in resulting consumer electronics from consumer-class computer SSDs down to embedded flash storage in the near future.

Samsung now mass producing 3D vertical NAND flash chips


Good for Samsung.... Let's see how Apple going to sue them because the corners of their chip has 90-degrees; exact same corners found on some Apple chips.

Don't worry-they'll spend millions trying and then Obama will smack them upside the head.

No Galaxy Note 3 for me. Been able to upgrade since March. But my Super Nexus GSIII just won't stop making me happy.

Just keeping paying that extra subsidy tony our carrier. #therichgetricher

Devil's advocate here.
"Following the logical progression along flash storage development,..."
Is this innovation?

Actually, it definition. It's taking something you have and making it better. Apple was plenty good at innovating too (not inventing as some would have you believe).

They're just taking Intel's innovation in 3D transistors and applying it to band storage....and then Apple will sue them...what?

Wow. Combine this with Samsung's Flash Friendly File System (F2FS) being implemented into Linux, which will eventually become the Android default filesystem (Google started Androidifying Linux 3.8, the first kernel with F2FS built in, as soon as it was released, something they don't normally do; that's strong evidence that they're very interested in F2FS), and Android I/O performance will be pretty much unbeatable within the next 2 years.

With all the junk low-end Android phones Samsung releases, at least they're doing something to advance smartphone technology.

See, Apple? This is what people call "innovation". Maybe you've heard of it?

The interesting thing about these chips is that maybe they will be able to produce devices with a far better range of storage capacities without compromising design or costs significantly.

Is it possible that in the past if you had 4 different storage sizes of phone then you might have spare empty memory slots on the smaller storage phones. This would waste space and if the 8GB models were your most popular you might still have to build them with wasted space to hold the empty locations to allow you to make a 64GB version. With a single slot I would expect that 8GB, 16GB, 32GB, 64GB etc models to be available without wasted space and therefore compromising the design.

I saw an article a few months ago about the same principle but applied to batteries. Was supposed to make batteries last ridiculously longer. I would have prefered to see that tech first. But hey, still great news!

So could this someday mean the end of 8Gb and 16gb devices?

Also, with Android 4.3's TRIM support, and the performance/reliability increase that comes along with these chips, won't we see a huge and noticeable leap in I/O?
