New Type NAND Chip - Sandisk QLC (TSOP48)

[Gregory]

You will get good plots on Sandisk v2 and Sandisk v5 (except last one). But it not help so much.

And RR for VNR can you check?
I have another and quality is very bad no see ECC.

What interesing, reading the first block pSLC in SLC mode, the sector is 1158_1154 and ECC is full geen.

OK, I have ECC 142B, confirm it is 1174_1170, XOR is from PS2251-09-V. In this chip bigest problem will be Read Retry
