Working Principles

X20C04P-15 is based on Electrically Erasable Programmable Read-Only Memory (EEPROM) technology. It utilizes floating-gate transistors to store and retain data. The memory cells can be electrically programmed (written) and erased using specific voltage levels applied to the control pins.

During a write operation, the desired data is stored by charging or discharging the floating gate of the memory cell. Erasing the memory involves removing the charge from the floating gate, resetting it to an unprogrammed state.
