    The GP521 uses EEPROM cells as the long term memory element. These cells will retain the stored data when the power supply is disconnected. Each EEPROM cell is combined with a temporary (RAM) memory cell which makes it possible to evaluate various control settings prior to saving them in the long term EEPROM memory.  |
