Unidirectional Error Correcting Codes for Memory Systems: A Comparative Study
In order to achieve fault tolerance, highly reliable system often
require the ability to detect errors as soon as they occur and
prevent the speared of erroneous information throughout the
system. Thus, the need for codes capable of detecting and
correcting byte errors are extremely important since many
memory systems use b-bit-per-chip organization. Redundancy
on the chip must be put to make fault-tolerant design available.
This paper examined several methods of computer memory
systems, and then a proposed technique is designed to choose a
suitable method depending on the organization of memory
systems. The constructed codes require a minimum number of
check bits with respect to codes used previously, then it is
optimized to fit the organization of memory systems according
to the requirements for data and byte lengths.
