Working Principles

The XC17256ELVO8I is based on EEPROM technology, which utilizes floating-gate transistors to store and retrieve data. The memory cells are organized into an array of rows and columns, with each cell capable of storing one bit of information. Data can be written by applying a high voltage to the control gate, which traps electrons in the floating gate, altering the transistor's behavior. Erasing the data involves removing the trapped charge from the floating gate using electrical pulses. The stored data can be read by sensing the transistor's conductance.
