Working Principles

AT29C020-70JC 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. The data is stored by trapping electric charges within the floating gate of each memory cell. These charges determine the binary state of the cell, representing either a "0" or a "1". The stored data can be accessed by applying appropriate voltage levels to the control pins of the device.
