Question

What type of memory does Arduino UNO and most microcontrollers have? a) Flash Memory and SRAM

b) ROM and DRAM
c) EEPROM and Cache Memory
d) NAND Flash and Registers

Answer 1

Arduino UNO and most microcontrollers have Flash Memory and SRAM.

Step-by-step explanation:

The memory type that Arduino UNO and most microcontrollers have is Flash Memory and SRAM.

Flash memory is a type of non-volatile memory that can be electrically erased and reprogrammed, making it suitable for storing program code. SRAM (Static Random Access Memory) is volatile memory that is used for temporary storage of data and variables during program execution.

For example, the Arduino UNO has 32KB of Flash memory, which is used to store the program code, and 2KB of SRAM, which is used for temporary data storage. Most microcontrollers, including the Arduino UNO, commonly feature Flash Memory and SRAM. Flash Memory serves as non-volatile storage for the program code, ensuring that the code persists even when power is removed. SRAM (Static Random Access Memory), on the other hand, provides volatile storage for variables and runtime data during program execution. This combination allows for both program storage and dynamic data manipulation. Unlike options b) ROM and DRAM, c) EEPROM and Cache Memory, and d) NAND Flash and Registers, the pairing of Flash Memory and SRAM accurately represents the prevalent memory architecture found in microcontrollers for efficient program execution and data handling.
