ABSTRACT:
When a DRAM enters an operation mode in which only a data storing operation is performed, a check bit for error detection and correction for plural data is generated and stored. Refresh operation is performed in a refresh cycle which is made long within an allowable range of an error occurrence by an error correcting operation using the check bit. Before the DRAM returns to the normal operation mode from the data holding operation mode, an error bit is corrected by using the data and the check bit.
