Find the memory error. Error. Error.

October 31, 2011



Which of these memory types are designed to detect errors? Pick two.

A) ECC

B) SDRAM

C) DDR

D) Parity memory

E) If you get a really powerful magnifying glass, you can find most memory errors yourself


The answer: A) ECC and D) Parity memory

Parity memory includes an additional parity bit that helps to identify errors, but it’s not designed to correct the error. Error Correcting Code (ECC) Memory can detect and correct memory errors on the fly.
