SanDisk Develops World’s Smallest 128Gb NAND Chip

By - Source: SanDisk | B 17 comments

SanDisk as developed a 128 Gb NAND Flash memory chip using 19-nm processing technology.

On Wednesday SanDisk said it developed the "world's smallest" 128 gigabit (Gb) NAND flash memory chip which is now in mass production. Built using SanDisk's 19-nm process technology, the chip uses SanDisk’s three-bit per cell (X3) tech that allows the company to build NAND flash memory products with the ability to read and write three bits of information in each memory cell.

So what does this all mean for the general consumer? More storage packed into the same form factors we know and love today like smartphones, tablets and even ultrabooks. The 128 Gb NAND flash memory chip can store 128 billion individual bits of information on a single silicon die 170-mm2 in size.

"At 19-nm, SanDisk is deploying its ninth generation of multi-level cell (MLC) NAND products and fifth generation of X3 technology," the company said in a press release. "This combination of manufacturing and technical expertise helps SanDisk pack more information into each memory cell making it possible to create a smaller, denser NAND flash memory chip."

In addition to the chip's announcement, the company also said it will be presenting a paper at the International Solid-State Circuits Conference (ISSCC) in San Francisco on Wednesday that outlines how its patented advanced all bit line (ABL) architecture was used to achieve an X3 write performance of 18 MB/s. The paper will detail how this achievement can be extended to certain product categories that use MLC NAND flash memory.

Products based on the 128 Gb three-bit per cell technology began shipping late last year, but SanDisk is just now starting to ramp into high volume production. The chip itself was developed jointly by teams from SanDisk and Toshiba at SanDisk’s Milpitas campus, led by Yan Li, director of Memory Design at SanDisk.

The team has also developed a derivative 64 Gb, X3 NAND flash memory chip based on the 128 Gb version which is compatible with the microSD format. SandDisk is ramping up the production of this chip as well.

    I seriously thought it was 128 GB, and after looking at the article closely, it's Gb. 128 Gb is 16 GB.

    Unless if it was a misprint. Or if I'm going insane.

    How much will this cost?

    128GB SD cards and 64GB micro-SD cards? Yes please. 'Course, I'm sure this stuff will be expensive for the near future...

    Actually, I already see a 64GB Sandisk micro-SD card on Newegg... for $130. It's out-of-stock, though.

    As far as I know you are not going insane. The article that is linked specifically says gigabit rather than gigabyte.

    Look how small it is!
    I think the picture induce us in error. I don't think this is going to be used in SSD. More likely going to be used for microsd/sdhc

    i dont know if this posted, so this may be a triple, sorry if thats the case. this time i'm removing all the math i did. this is the last post, if it doesn't show up this time, ill write it off as i for a sanction and just haven't been told yet.

    i just did the math,

    so with that math, and its rough math, i have estimated the cost per gb to be .93 cents

    now if only i could get this on ssd quality memory, would love to find out how much we are being screwed if we are at all.

    As long as they don't try to put this crap in SSDs, I'm all for it.

    its too slow for ssd.

    aidynphoenixits too slow for ssd.

    SSDs tend to use multiple flash ICs in multi-channel to boost the speed. And each flash IC can contain 4 or even more of these chips. If you do the math, that can still come out to around 570MB/s theoretical speeds with just 8 ICs.

    NAND chip capacity are mentioned in gigabits just like RAM/VRAM. Chips like these will be packaged with controller to get a SSD or pendrive. Since it's a 3-bit NAND, write speeds will be slow and write amplification will go through the roof. IMO these chips will be only used in pen drives and memory cards.

    Must be a unreliable chip for them to not mention how much data can be written to it before killing it.

    Okay, what exactly am I missing here? I have a 16GB MicroSD card in my Droid X. When I take it out, the thick part of the chip (which houses the actual silicon) looks smaller than this chips stated size of 170mm2 (or roughly 13 x 13 mm, or one half-inch square). I'm sorry, but 16GB stored in a half-inch? Don't we already have this?

    And if it IS for SSD, then why haven't they been using existing MicroSD technology to populate multi-channel SSD lanes already? SOMEBODY EXPLAIN WHICH PART OF THIS IS NEW AND EXCITING!!!

    According to article they started shipping last year, however due to the rotation of Earth we just now got the news.

    southernsharkHoly Cow... 128gbs... on that? Awesome.

    ?? 128 Gbit/chip. 18 MByte/sec. Either you misread it, or 18 MB/s equals 128 gbit/sec, or I missed a conversion factor having to do with the number of chips used in an SSD.
