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 ...

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 ...

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 ...

In teaching students about how to compute the likelihood of failure of complex systems in which all components must function correctly for the system to work (or, put another way, where failure of one ...

(click thumbnail)Fig. 1: Red characters represent corrupted packets.Error detection and correction technologies are crucial. They are present on every CD, DVD and ...

As memory bit cells of any type become smaller, bit error rates increase due to lower margins and process variation. This can be dealt with using error correction to ...

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 ...

The digits zero and one are the natural language of computers. Almost anything can be represented inside a computer's memory simply by arranging zeros and ones into the proper sequence. However, ...

Hi,<BR><BR>I have a Linux MD RAID 5 array formed out of five Western Digital SATA drives connected to two Promise TX4 SATA controllers (four drives on one controller, one drive on the other). On top ...
