TSOP48 Extra Power Adapter for NAND Data Recovery
In NAND data recovery, the TSOP48 is probably the most popular NAND chip package, making it possible to encounter various differences between chips. In some cases, adjusting the voltage on Vcc and VccQ can assist in reading the NAND chip. However, ...
AU Monolith Devices with Bad Pages
In the market for USB flash drives, many monolithic devices can be found. Often, these devices contain Alcor Micro (AU) controllers. While most of them function in a standard way, some exhibit unique characteristics. It is possible applied XOR, bit ...
How to use monoUFD 6×6 & 3×7 adapter
Monolithic USB drives and memory cards are widely used in various devices, but data recovery from these media can be more challenging than from standard BGA NAND chips. In such cases, specialized adapters play a crucial role, allowing safe ...
NAND Memory Protocols: The Difference Between SDR and DDR
Everyone who works in NAND data recovery knows that reading NAND requires using a protocol. The most popular protocols are Async and WL. Almost all protocols have two versions: SDR and DDR. 1. Protocols in reader configuration What is SDR and DDR and ...
Block Rotation element for Phison and Sandisk devices
The VNR has a user-friendly Block Rotation element, in almost all Phison and Sandisk cases that have rotation inside blocks. It is a simple way to reverse it. To make an element even easier to use, we will explain how to determine what kind of ...
