Chip reading
Missing data planes in TSOP48, LGA52, BGA132 and BGA152 Sandisk chips.
This article shows the way how to extract all data from TSOP48, LGA52, and BGA132/152 Sandisk memory chips when the configuration and dump size are correct, but half of the dump is still empty. Usually, if a NAND memory chip has 2 or 4 crystals, ...
Why should you throw away your hot air station for unsoldering
There’s one long-lasting debate about memory chip unsoldering – what’s the best technique? Our users constantly ask us about using a hot air station to unsolder memory chips. We'd like to explain in 'simple terms' why using a tool like this can ...
Inter-page shifts
Inter-page shifts The shifted pages during memory chip reading isn’t a regular situation, but sometimes in some cases with specific devices, this problem may appear. In this article, we will show you why exactly this problem occurs and how to easily ...
Reading BGA132/152
High capacity BGA 132/152 chips have complex pinout which includes 2 lines of data buses and two groups of 4 CE (Crystal) signals which are connected separately to the first and the second data bus. This solution guarantees high speed of read/write ...
Analysis of bit errors in NAND and power adjustment
During the NAND chip reading process, there are internal noise and interference occur, which results in bit errors and data corruption. This problem is particularly critical for TLC flash chips. If a physical image extracted with a high number of bit ...
Chip reading
Reading dumps from chips Visual inspection of memory chip should precede plugging it to the Reader and adapters. Checking pins and pads is a mandatory process. Bent pins should be adjusted properly. In case of severe damage (e.g. broken pins ...
ECC in NAND flash memory
All modern flash storage devices have a problem with data integrity caused by a poor quality of the NAND chips. This problem is well known as “Bit errors”. When bit errors appear within the area where file is stored, it gets corrupted and unreadable. ...
