And that’s where the ACE Lab Spider Board Adapter comes in. The first thing you should know – the chip-off is not an option here. Let’s explore the process of data recovery on the example of a Phison PS-based USB drive with the COB NAND chip that we have in our lab: So what can you do if a NAND Flash drive with the eMMC chip that has a disabled controller, the COB controller, or even the COB memory chip ends up on your desk? In this article, we will show you the unique way to handle these untypical but commonly encountered cases. And even if you succeed, it doesn’t mean that you can read data from such a chip. The procedure of coating removal is very dangerous since you can easily damage the NAND core.
The main obstacles lie in their internal structure: under the coating of black plastic, there is just a NAND crystal with small traces connected to the PCB. The COB (Chip On Board) memory chips present a challenge to data recovery engineers trying to recover data from them.
