Working Principles

The AT29LV040A-20TI utilizes Flash memory technology, which is based on the principle of electrically erasable programmable read-only memory (EEPROM). It stores data by trapping electrons in a floating gate within each memory cell. The presence or absence of these trapped charges determines the binary state of each memory cell, representing either a "0" or a "1". Data can be written to and read from the memory cells using appropriate voltage levels and control signals.
