There are situations when you are reading a chip and see a detected Chip ID but it cannot be applied in the Task. As a result, it doesn’t allow to read the dump from the memory chip. Such behaviour may be if:
► The chip has physical damages or was overheated during the unsoldering process
► The memory chips reference book doesn’t have reading parameters for a certain Chip ID.
The information below will be useful when adding read parameters for new (unknown) memory chips and is intended for users who understand the main principles of NAND.
If you are new in NAND data recovery, we recommend studying these principles first.
Of course, you can try to find a datasheet for a certain memory chip and take reading parameters from there. But sometimes there is no possibility to find that datasheet or some parameters are missing there (not described).
Reading parameters detection is an investigation process and requires some specific knowledge. In this article, we’ll overview some ideas that can be helpful for you during this process. Anyway, we strongly recommend to contact our Technical Support Department if you get an unsupported NAND ID during your data recovery process.
