This is BiCS NAND Close Up from Kioxia and Sandisk

What happened

This is BiCS NAND Close Up from Kioxia and Sandisk, according to ServeTheHome. For those who do not know, BiCS NAND is a joint endeavor by Kioxia and SanDisk. This is BiCS NAND Close Up from Kioxia and Sandisk Starting off, here is the wafer (the disc of silicon that chips are cut from) that Kioxia showed of the BiCS FLASH Generation 10 1Tb TLC NAND.

It operates with CBA technology and has 332 layers. Next to it, you can see a die cross section and a microscope.

This is just a really neat cross-sectional view of how the NAND is built. You may think everything is straight up and down, but on the left side you can see that they are actually offset a bit.

On the top, you can see the package balls as well for a sense of scale. Sandisk also had a wafer on display.

Here, you can see the tiny wires going between the different layers. You can get a sense of just how small those wires are between the layers, and they are something you would not normally see even just looking at the package from a distance.
