DP8404, DP8402A, Error Detection and Correction Circuits
The DP8402A DP8403 DP8404 and DP8405 devices are 32-bit parallel error detection and correction circuits (EDACs) in 52-pin DP8402A and DP8403 or 48-pin DP8404 and DP8405 600-mil packages The EDACs use a modified Hamming code to generate a 7-bit check word from a 32-bit data word This check word is s
