Working Principles

The AT27LV256A-15RC utilizes electrically erasable programmable read-only memory (EEPROM) technology. It stores data by trapping charges within a floating gate structure, which can be electrically programmed or erased. When data is written, an electrical charge is applied to specific memory cells, altering their state. This stored charge represents the binary information. During read operations, the stored charge is sensed, allowing the retrieval of
