Working Principles

The AT27LV040A-90JU utilizes flash EEPROM technology to store and retrieve digital information. It consists of a grid of memory cells that can be electrically programmed and erased. When data is written, the memory cells are programmed by trapping charges in the floating gate, representing either a "0" or a "1". The stored data can be read by applying appropriate voltage levels to the memory cells. The non-volatile nature of this memory allows for long-term data retention.
