68. ECC Memory、Error Correction
#CC-06-068
中
ECC Memory
Error Correction
📝
☆
Which of the following statements regarding ECC (Error-Correcting Code) memory are accurate?
A
ECC memory modules have an extra memory chip compared to non-ECC modules, which stores the parity bits used for error detection and correction.
B
DRAM-based memory systems usually employ advanced ECC mechanisms, like LDPC or BCH codes, capable of detecting and correcting multiple-bit errors to ensure data integrity and reliability.
C
The performance overhead introduced by ECC memory is negligible in modern systems due to advancements in memory controllers.
D
ECC memory relies on redundancy in data encoding to perform error detection and correction.
E
None of the above
