Summary:In order to correct an error in input data to thereby obtain write data, in a memory core, an EXOR element performs arithmetic processing based on an output result of an output data latch for latching read data and a result of inputted array input data, and a selector selects a result of the arithmetic processing to prepare write data. Thus, data obtained after performance of the arithmetic processing can be generated in a semiconductor memory by an operation performed immediately after data read. In addition, it is unnecessary to transfer data to an external logic circuit. Therefore, the result of the arithmetic processing can be written to a memory cell block in a subsequent clock.
