Can "Sector-Level" techniques be used for chip-off analysis?

Sector-level techniques are not applicable for chip-off analysis because this method involves physically removing a chip from a device to access the raw data stored on it. Unlike logical or file system analysis, which can utilize sector-level techniques to read data from a device in its intended operating environment, chip-off analysis focuses on directly extracting data from the memory chip itself after it has been decoupled from the device.

Unique to chip-off analysis, forensic examiners work at the physical level of the hardware and typically employ techniques such as micro soldering and specialized hardware to read the memory content. Because this process bypasses any logical structures that sector-level techniques rely on, it becomes clear why sector-level techniques cannot be used in this context. Instead, the data extracted from the chip is typically processed through specialized software that can interpret the raw binary data without using logical sector structures, making sector-level approaches irrelevant in this specific scenario.
