描述 Description

The Intersil ACS630MS is a Radiation Hardened 16-bit parallel error detection and correction circuit. It uses a modified Hamming code to generate a 6-bit check word from each 16-bit data word. The check word is stored with the data word during a memory write cycle; during a memory read cycle a 22-bit word is taken form memory and checked for errors. Single bit errors in the data words are flagged and corrected.
