Direct access to NAND and physical image extraction

Direct access to NAND memory and physical image extraction The Visual Nand Reconstructor supports two modes of access to memory chips: 1. Direct access to NAND memory (used for scrambler (XOR key) extraction, bit errors estimation, bad columns removal, power adjustment) 2. Physical image extraction (used for logical image reconstruction and data recovery) When new…

Logical image reconstruction

Logical image reconstruction When physical image of chip extracted to file it’s stored in “Physical image” element. In this case pendrive had one NAND chip that consisted of one crystal. At beginning of analysis it’s necessary to describe structure of NAND physical image. It helps to visualize patterns and determine parameters such as Block size,…
