Abstract
PURPOSE: To increase using efficiency of a memory module, by performing an error check by identifying the addition of a error correcting code or the parity for reading data given from a memory part.
CONSTITUTION: The device is provided with the data memory part 2; data writing control part 3; data memory device control part 4; and data correction/output part 6 respectively. The output part 6 checks the presence or absence of the error based on the control signal supplied from the parity identifying part 5 as well as the error correcting code ECC in case the data read out of the part 2 contains the parity, and at the same time delivers the reading data. On the other hand, the presence or absence of the error is checked in case the readout data contains ECC. Then the data is corrected when the 1-bit error exists to be delivered, and the presence of the 2-bit error is detected in the case of the 2-bit error.
