REVIEW ON A DECODER FOR SHORT BCH CODES FOR EMERGING MEMORIES

Abstract

These emerging memories also struggle with reduced reliability as technology scales down, and as a solution, error-correcting code (ECC) and its encoder / decoder circuits have been applied. While NAND flash requires a powerful ECC that can correct up to 100 errors, As well as simply increasing the memory capacity, ECC can be used to optimize memory performance with regard to density and energy consumption, The ECC has thus become an essential part of developing memories. The Bose – Chaudhuri – Hocquenghem (BCH) software is commonly used for evolving memories to correct two or three errors.
