Hi all! Was wondering if anyone has any info on a Toshiba NAND IC I am working with (not for a case or data recovery, just playing around and practicing) It is a TH58NVG7D2HTA20 (there are 7 of these from some torn down SSD I found). Can't find a datasheet specifically for this IC. ID is 98DEA48276. Rusolut VNR has the ID in its database but refers to it as a TC58NVG6D2HTA00. When looking at the dump (before and after a read), something just seems off. Any pointers or anyone ever come across this IC before? Thanks! |

It doesn't answer your question, but the attached document has ~700 NAND chip IDs.

You can try and find similar datasheets and see if they list a READ ID, and include multiple chip numbers. or looking at a part number decoder might give you some insight. Newer Toshiba chip datasheets not that easy to find. Some chips I think may be produced for a certain vendor, and thus not widely distributed.

So if this is correct, the differences between the VNR config and your chip appears to be: TH 58NV G7 D2HTA 20 - Multi Chip | G7 128(=27 ) Gbits =16GB | Single Channel, 2 /CE TC 58NV G6 D2HTA 00 - Single Chip | G6 64(=26 ) Gbits =8GB | Single Channel, 1 /CE |

Found this site that decodes partnumbers... https://nand.gq/#/decode might be interesting for people investigating flash stuff. this is the project: https://github.com/iTXTech/FlashDetector iTXTech FlashDetector Universal NAND Flash Part Number Decoder and Search Engine.

Thank you so much for sharing! I am getting closer to solving it. Like I mentioned, the 7 ICs I have were already removed from what ever SSD they were originally attached to, so I am not sure exactly what controller was on it, but It seems like it was probably a JM. SA is XOR'd, but looks like I might have to extract the key manually as VNRs XOR analyzer is not finding the correct match. To be fair, I don't have much experience with SSDs. People always send me the totally obscure stuff (old NAND, software controlled, etc.) so I have been trying to give myself some experience with more common stuff by practicing. Again, thanks so much for the resources, these are great tools! |

No worries, Sharing is Caring! If you have VNR, maybe support can help |
