REG 와 ECC 를 다음과 같이 보고있습니다. 참조만 하세요...
Q. Is all registered SDRAM also ECC?
A. Yes and no.
Registered SDRAM does not necessarily have to be ECC. However, at Crucial,
we\'ve found that our customers who purchase registered SDRAM also want ECC. As a result, all of the registered SDRAM we sell at Crucial.com is also ECC.
그리고 ECC 에대한 내용을 잠시 언급하면..
Q. Are ECC and parity the same thing? If not, what\'s the difference?
A. No. Although they both detect memory errors,
ECC and parity are not exactly the same.
Parity modules detect single-bit data errors.
Error correcting code (ECC) modules detect and correct single-bit errors, and they detect and report double-bit errors. FPM and EDO modules can be parity or non-parity. SDRAM and DDR modules can be ECC or non-parity (also called non-ECC).
