Working Principles

M25P80-VMW6 utilizes flash memory technology to store data. It consists of multiple memory cells organized into sectors. Each memory cell can store one or more bits of information using electrically isolated floating gates. The state of each memory cell is determined by the presence or absence of an electric charge on the floating gate.

During read operations, the stored data is accessed by applying appropriate voltages to the memory cells and sensing the resulting electrical currents. Write operations involve erasing and programming memory cells using specific voltage levels and timing sequences.
