Working Principles

The 24AA64F-I/P utilizes EEPROM technology, which consists of a grid of memory cells that can be individually programmed or erased. It operates based on the principle of injecting charge into floating gate transistors to store data. The stored charge determines whether a memory cell represents a logical "0" or "1". Reading, writing, and erasing operations are performed by applying appropriate voltage levels to the memory cells.
