Protecting Memories against Soft Errors: The Case for Customizable Error Correction Codes

نویسندگان

چکیده

As technology scales, radiation induced soft errors create more complex error patterns in memories with a single particle corrupting several bits. This poses challenge to the Error Correction Codes (ECCs) traditionally used protect that can correct only bit errors. During last decade, number of codes have been developed emerging patterns, focusing initially on double adjacent and later three burst However, as memory cells get smaller smaller, created by will continue change thus new be needed. In addition, layout may also make some likely than others. For example, memories, there maybe elements separate blocks bits word, making affect two less likely. Finally, for given memory, depending data stored, critical if numbers are stored most cases, significant larger impact. Therefore, application, achieve optimal protection, we would like code corrects set patterns. is not possible today limited choices available terms correctable word lengths. linear block regular structure which design automated. this paper, propose automation correction protection. To end, introduce software tool length need corrected, produces described its parity check matrix placement. The benefits automated approach illustrated case studies. made so designers easily produce custom their specific needs.

In this paper “Protecting data against isolated defects and soft errors using low delay single error correction codes” we proposed memories can be protected from soft errors by using error correction codes. Single error correction (sec) codes correct 1-bit error per word. In some condition, SEC codes are extended to detect double error are known as single error correction double error detection...

Coping with Bit Errors using Error Correction Codes

Recall our main goal in designing digital communication networks: to send information reliably and efficiently between nodes. Meeting that goal requires the use of techniques to combat bit errors, which are inevitable in both commmunication channels and storage media (storage may be viewed as “communication across time”; you store something now and usually want to be able to retrieve it later)....
