Working Principles

AT29LV256-20JI utilizes flash memory technology, which stores data by trapping electric charges within floating gate transistors. The presence or absence of these charges determines the stored information. When reading data, the memory controller applies appropriate voltages to the memory cells and measures the resulting electrical currents to determine the stored values. During write operations, the controller applies higher voltages to modify the charge levels in the floating gates.
