It is common practice to use rewritable non-volatile memory – such as UV-EPROM or EEPROM – for the development phase of a project, and to switch to mask ROM when the code has been finalized.
Uobičajena je praksa da se koristi ponovo upisiva memorija – kao što je UV-EPROM ili EEPROM – u toku razvojne faze projekta, a zatim da se pređe na mask ROM kada se kodiranje završi.
