3D NAND is more difficult to make than previously thought. Unlike 2D NAND, which is a planar structure, 3D NAND resembles a vertical skyscraper. A 3D NAND device consists of multiple levels or layers, which are stacked and then connected using tiny vertical channels. Today’s leading-edge 3D...
I am trying get Eboot to read a file on the DOS/FAT partition residing on the NAND flash on my AM335x EVM board. For an SD card it's easy: it's described in sdcard.c. How does one do this for the NAND flash (get Eboot to read a file fr...
no, secure erasing an ssd drive is designed to make data recovery nearly impossible. the process involves overwriting the entire drive with random data or zeroes, making the original data effectively unrecoverable. this is why it's crucial to have proper backups before performing a secure erase,...
As a result, NAND flash can "rot" into a read-only state. Some manufacturers use something called wear-leveling to counteract the degradation of NAND flash. This technique distributes data writes across all blocks to make sure the flash memory wears evenly, but even with that, SSDs will ...
(and relatively expensive) DRAM and less costly, non-volatile NAND Flash. While a revolution in its day, NAND Flash has comparatively high latency (the delay between an input/output (I/O) request and the resulting response from a drive), leading some advanced users, such as gamers, to ...
Using NAND is worse than using microSD card because: you need more software knowledge, especially regarding file systems; it is harder to make a backup; in case of a problem with the file system – the device would not boot and the recovery (of your data) would be nearly impossible. ...
The stairstep etch is yet another very difficult and new process that must be managed to successfully mass produce 3D NAND. The vias must land precisely on their designated stairstep and not on any others, or the wordlines will be shorted to each other. If the via doesn’t make a solid...

This is why it’s important to look at the reliability of a total storage system on a case-by-case basis rather than make blanket assumptions based on components alone. How Pure Storage Leverages 3D NAND to Deliver Custom Solutions for Your Needs As a pioneer in all-flash storage solutions...
