Working Principles

The M29W128GH70N3E utilizes NAND flash memory technology to store and retrieve data. It consists of multiple memory cells organized in a grid-like structure. Each cell can store multiple bits of data by varying the electrical charge on its floating gate.

During programming, an electric charge is applied to the floating gate, trapping electrons and altering the cell's threshold voltage. This change in voltage represents the stored data. Erasing is achieved by removing the trapped charge from the floating gate, resetting the cell to its initial state.

Data access and manipulation are facilitated through the SPI interface, which allows for serial communication between the flash memory device and the host system.
