Working Principles

The M25P40-VMN6 operates based on the principles of flash memory technology. It utilizes floating-gate transistors to store digital information as electrical charges. These charges are trapped within the transistor's floating gate, representing binary values (0s and 1s). The state of each memory cell is determined by the presence or absence of these charges.

During read operations, the stored charges are sensed, and the corresponding data is retrieved. Write operations involve applying a high voltage to the memory cell, which allows charges to be injected or removed from the floating gate, altering its state.
