ROMis a type of memory that does not lose its contents when the power is turned off.Different types of ROM are PROM, EPROM, EEPROM, Flash EPROM, and maskROM. The CPU is connected to RAM and ROM using the address bus, data bus, andcontrol bus.RAM: Stands for random access memory; refers to memory that the microprocessorcan read from and write to. Program variables and data as well as stack data storageare saved in RAM of the microcontroller.ROM: Stands for read-only memory. The microcontroller can read from ROM, but itcan’t write to or modify it.EEPROM: One type of ROM is EEPROM, which is Electrically ErasableProgrammable ROM. Variables that must remain when the power is turned off arestored in EEPROM.Flash memory: A special type of memory that works like both RAM and ROM. Youcan write information to flash memory, like you can with RAM, but that informationisn’t erased when the power is off, like it is with RAM. All program code, constantssuch as messages and lookup tables, and any other information that does not change,are saved in flash memory of the microcontroller.Course Number: ECET330Laboratory Number: 1 (Part 1)Page 1 of 5
