ABSTRACT:
A read circuit is connected to bit lines of different cell arrays in common, and determines a logical value of data read out onto any bit line of the cell arrays. An error correcting circuit corrects an error in the data read out onto a common read data line, and outputs the data as corrected data. In order to write back the corrected data into a memory cell from which the corrected data has been originally read out, write switches connect a common write data line through which the corrected data is transmitted, to a corresponding bit line. Thus, during a read cycle the corrected data can be written back to the memory cell.
