As with any electronic system, errors in the memory subsystem are possible due to design failures/defects or electrical noise in any one of the components. These errors are classified as either ...

FEC (forward error correction), a critical component of many modern digital-communications applications, turns otherwise-unusable links into real and practical ...

Several techniques can be used to efficiently implement a Hamming coder for single-bit error correction and double-bit error detection. Many error-correcting codes ...

Correction is not possible with one parity bit since any bit error in any position creates exactly the same information as bad parity. If more bits are integrated ...

The Google servers use ECC DRAM that typically corrects single bit errors and reports double bit errors. It is a rare notebook or consumer desktop that supports ECC. You could be having DRAM problems ...

I got into an argument with a colleague about RAID levels (specifically RAID5) and whether the redundancy was accomplished through parity or ECC. The standard sources all refer to the RAID5 array ...
