Working Principles

The AT49LV002T-12PI utilizes flash EEPROM technology to store and retrieve digital information. It consists of a grid of memory cells, where each cell can store a bit of data. These cells are organized into rows and columns, forming an addressable array. When data needs to be stored, the device applies a high voltage to the appropriate memory cells, causing them to trap electric charges. To retrieve the stored data, the device reads the electric charges from the memory cells and converts them back into digital information.
