Abstract
Input data (A) having an integral multiple of 8 bits is divided into symbols in units of b bits (b is an integer of 5 to 7) in a register file, an error detecting code is added in an error detection calculation circuit, and then encoding (such as Reed Solomon (RS) encoding) having an error correction capability of two or more symbols is performed in a parity calculation circuitto record the data in a storage. In the reproduction, error correction in units of symbols is performed to reproduced data from the storagein an error correction circuit, error detection processing is performed in an error detection calculation circuit, and then data having the integral multiple of 8 bits is recovered in a register fileto output the same. By this means, it is possible to provide a storage system with high reliability to a soft error that occurs in a storage such as semiconductor memory.
