Working Principles

The AT49LV002T-90JC utilizes flash EEPROM technology for data storage. It consists of a grid of memory cells that can be electrically programmed and erased. The device uses a combination of transistors and floating gate structures to store and retrieve data. When data is written, charges are trapped in the floating gate, altering the cell's electrical characteristics. These charges can be removed during an erase operation, allowing the cell to be reprogrammed with new data.
