Boise, Idaho–based memory manufacturer Micron Technology says it has reached volume production of a 232-layer NAND flash-memory chip. It’s the first such chip to pass the 200-layer mark, and it’s been a tight race. Competitors are currently providing 176-layer technology, and some have said they are on track to follow Micron’s skyward move or already have working chips in hand.
The new Micron tech as much as doubles the density of bits stored per unit area versus competing chips, packing in 14.6 gigabits per square millimeter. Its 1-terabit chips are bundled into 2-terabyte packages, each of which is barely more than a centimeter on a side and can store about two weeks worth of 4K video.
With 81 trillion gigabytes (81 zettabytes) of data generated in 2021 and International Data Corp. (IDC) predicting 221 ZB in 2026, “storage has to innovate to keep up,” says Alvaro Toledo, Micron’s vice president of data-center storage.
The move to 223 layers is a combination and extension of many technologies Micron has already deployed. To get a handle on them, you need to know the basic structure and function of 3D NAND flash. The chip itself is made up of a bottom layer of CMOS logic and other circuitry that’s responsible for controlling reading and writing operations and getting data on and off the chip as quickly and efficiently as possible. Improvements to this layer, such as optimizing the path data travels and reducing the capacitance of the chip’s inputs and outputs, yielded a 50 percent improvement in the data transfer rate to 2.4 Gb/s.

An amazing achievement
I wonder how fast areas of memory go bad on these chips.
The multi layers and heat cause memory failure in hotspot areas of chips like this.
Just...
Wow. That really is impressive.

I’ve paid for that over the last 30 years....
I’m not impressed. My porn collection is 50 times that.
Now if we could get some chips to finish out the tech options on our new cars - that would really be impressive
Way back in the 80’s I lived in the Silicon-Pit and worked in the world of “Bleeding Edge” tech.
Anything that is ground-breaking today is obsolete in less than five years.
I personally do not see ever increasing speed and memory capability as a positive trend overall.
Even in the 80’s some of us were concerned about the loss of freedom such capabilities would enable.
Then the Gov. spying was revealed, or I would say confirmed.
A long while back at Intel, we built a 16K memory for IBM
by stacking two 8K’s in 18 pin cerdips and using the 17th
pin for chip select. I feel old.
I now firmly stay 10 years behind the bleeding edge.
Now I’ve saved 10s of thousands of dollar$ in the last few years..
Peeps used to be very inventive.
Git ‘er done [reliably].
More technology to control us with.
We used to build memory chips with ‘extra’ cells and patch them in to cover bad spots. (redundancy)
With these massively dense 3-d memory chips its kind of a different ballgame in terms of size and the way heat affects them, and how hotspots develop.
I remember when the first Mac came out. it had a 128k of Ram and no hard drive, just floppy discs. That was in 1984 - just 38 years ago.
Amazing the progress that has been made!
I take it these chips are not cheap.
(By the way, I like your handle - FarCenter - clever :) )

That is breathtaking. Wow.
