N2 - A double error correcting (DEC) BCH codec is designed for NOR flash memory systems to improve reliability. Due to the latency constraint less than 10 ns, the fully parallel architecture with huge hardware cost is utilized to process both the encoding and decoding scheme within one clock cycle. Notice that encoder and decoder will not be activated simultaneously in NOR flash applications, so we combine the encoder and syndrome calculator based on the property of minimal polynomials in order to efficiently arrange silicon area. Furthermore, a new error location polynomial is developed to reduce the number of constant finite filed multipliers (CFFMs) in Chien search. According to 90 nm CMOS technology, our propose DEC BCH codec can achieve 2.5 ns latency with 41,705 μm 2 area.
