Q92 / 100
What is the purpose of "ECC" (Error-Correcting Code) memory in some embedded systems, especially those operating in harsh environments (e.g., aerospace)?
Correct! Well done.
Incorrect.
The correct answer is A) ECC memory can detect and automatically correct certain bit errors caused by phenomena like cosmic radiation (bit flips), improving reliability in environments where memory corruption risk is elevated
A
Correct Answer
ECC memory can detect and automatically correct certain bit errors caused by phenomena like cosmic radiation (bit flips), improving reliability in environments where memory corruption risk is elevated
Explanation
In environments with elevated radiation (e.g., high altitude, space), random bit flips in memory ("soft errors") become more likely; ECC memory uses additional bits to detect and correct single-bit errors, improving data integrity.
