Abstract
The developments in IC technology and rapid increase of transistor densities and scaling factor, the use of ECC’s acquired prominence. Multiple bit errors in memories due to technology scaling demands advanced error correction codes. SEC-DEC, DEC, burst error detection, Golay code, Reed Solmon codes etc. have much decoding complexity and latency. The above drawbacks can be reduced with OLS codes. OLS codes with majority logic decoding technique, modular construction and simple decoding mechanisms it enables low delay improvements. MBU’S can be addressed using OLS-MLD codes. This paper presents a detail study of developments in multibit ECC’s using OLS-MLD mechanism
