Working Principles

MT28F400B3SG-8 TET utilizes NAND flash memory technology. It stores data in a series of memory cells organized in a grid-like structure. Each cell can store multiple bits of information using multi-level cell (MLC) or triple-level cell (TLC) technology.

During write operations, the flash memory applies high voltage to the selected memory cells, causing electrons to tunnel through an insulating layer and get trapped in the floating gate. This trapped charge represents the stored data.

During read operations, the flash memory applies appropriate voltages to the memory cells and measures the resulting electrical current. The magnitude of the current indicates the stored data value.
